Wuhan Desheng Biochemical Technology Co., Ltd

The 13th Munich Shanghai Analytical Biochemistry Exhibition will kick off at the Shanghai New International Expo Center from November 16th to 18th, 2026. This exhibition covers halls N1-N5 and E6-E7, with a display area of nearly 85000 square meters, and is expected to gather over 1100 exhibitors. Among them, pavilions N3, N4, and N5 are the "Life Sciences, Biotechnology, and Diagnostics Exhibition Area", showcasing cutting-edge products and solutions in the fields of clinical diagnosis and life sciences. Hubei Xindesheng Material Technology Co., Ltd. will showcase its full range of IVD reagent raw materials and blood sample pre-processing products at booth 4113 in Hall N4, and discuss with upstream and downstream partners the stable supply and advanced localization of diagnostic raw materials. The determination of a raw material enterprise In 2025, the Department of Economy and Information Technology of Hubei Province announced the list of provincial-level manufacturing industry champions, and Hubei Xindesheng was selected based on its long-term deep cultivation in the subdivision field of IVD reagent raw materials. This recognition focuses on enterprises that have long been dedicated to specific niche areas, have a leading market position in their products, possess sustained innovation capabilities, and improve their quality control systems. For an upstream raw material enterprise, this recognition points precisely to the few things that the diagnostic industry cares most about: whether the product is stable, whether the batch is consistent, and whether the supply is sustainable. The predecessor of New Desheng can be traced back to Wuhan Desheng Biochemical, which was established in 2005. It is one of the earliest enterprises in China to develop and produce blood collection tube additives. After more than 20 years of accumulation, the company has established two large-scale production bases in Gedian and Huanggang, with an annual production capacity of 5000 tons for all product categories. It has the ability to undertake from research and development trials to large-scale production. What to watch on the booth: Focus on the two main lines of "sample pre-processing" and "reaction system" At booth N4-4113, Xindesheng's exhibition will revolve around two key links in the upstream of the IVD industry chain. Firstly, pre-processing of blood samples. The additives in vacuum blood collection tubes directly affect the reliability of subsequent inspection results. New Desheng has formed a product system represented by heparin lithium, heparin sodium, EDTA dipotassium/tripotassium, serum separation gel, and coagulant, covering core scenarios such as anticoagulation, coagulation, and serum separation. For blood collection tube production enterprises, the purity, inter batch consistency, and adaptability of additives are the basic links to ensure sample quality. Secondly, the core raw materials of diagnostic reagents. In the field of biological buffering agents, Xindesheng provides dozens of commonly used and customized varieties such as Tris, HEPES, MOPS, etc. The product purity can reach over 99%, and the inter batch difference is controlled within a certain range to maintain the stability of the pH environment of the reaction system. In the direction of chemiluminescence and color development, luminol, isoluminol, acridine ester, and a series of color substrates cover the raw material requirements for chemiluminescence immunoassay and biochemical diagnosis. In addition, product lines such as enzyme preparations and Carbopol will also be showcased on-site for data display and demand matching. Why is it worth coming to N4-4113 to talk about The value of the Munich Biochemical Exhibition lies not only in showcasing new products, but also in showcasing the true supply capability of upstream raw materials. Diagnostic reagent companies are concerned about whether key raw materials can break away from single source dependence, whether batch differences can be controlled, and whether customized needs can be quickly responded to. New Desheng's accumulated process experience in the field of blood collection tube additives and biological buffering agents, as well as its long-term practice of "domestic substitution and independent supply", perfectly correspond to these practical problems. During the exhibition, the New Desheng technical team will have face-to-face communication with visitors on specific issues such as raw material selection, system adaptation, and customized development at the booth. Booth Information Exhibition: 2026 Munich Shanghai Analytical Biochemistry Exhibition Time: November 16-18, 2026 Location: Shanghai New International Expo Center (No. 2345 Longyang Road, Pudong New Area) New Desheng booth: Hall N4-4113   In late autumn Shanghai, N4 Hall 4113, Xindesheng has prepared product information and process ideas, waiting for you to chat about some specific details.

From November 16th to 18th, 2026, the Munich Analytical Biochemistry China Exhibition (analytica China 2026) will be held at the Shanghai New International Expo Center. As an important exhibition in the fields of analysis, biochemistry, and laboratory technology in Asia, analytica China gathers global instrument manufacturers, reagent suppliers, research institutions, and laboratory end-users. It is an important window for observing technological trends and connecting upstream and downstream resources. For biochemical raw material enterprises, this exhibition is not only a place to showcase products, but also an opportunity for face-to-face communication with downstream users such as reagent development, inspection and testing, scientific research experiments, etc. Hubei Xindesheng Material Technology Co., Ltd. has confirmed its participation in the exhibition, with booth number N4-4113. The company will showcase its core product matrix, including biological buffering agents, blood collection tube additives, chromogenic substrates, and enzyme preparations, targeting application scenarios such as in vitro diagnostics, biomedicine, and laboratory research, demonstrating the supply capability and technological accumulation of domestic biochemical raw materials. Exhibition Preview: Biochemical Raw Material Matrix Covering Multiple Scenarios At this exhibition, Xindesheng will focus on showcasing several types of products closely related to laboratory analysis and biochemical research. In terms of biological buffering agents, more than 50 products including TRIS, HEPES, MOPS, CAPS, TAPS, etc. form a matrix with a stable purity of over 99%. The indicators can be customized according to customer application scenarios. Buffer agents may seem basic, but they directly affect the pH stability of experimental systems such as electrophoresis, chromatography, and cell culture. The pKa range, temperature dependence, and metal ion complexation tendency of different buffering agents vary. Whether the selection is matched often affects the experimental reproducibility and inter batch consistency of the reagent kit. The blood collection tube additive series is also a key focus of the exhibition. More than 20 products including serum separation gel, heparin lithium, heparin sodium, EDTA dipotassium/tripotassium/disodium, coagulant, coagulant powder, etc. support one-stop procurement to serve the formulation and process needs of blood collection tube production enterprises. This type of product requires high batch stability and coating performance, and the on-site technical team can communicate with customers based on their actual production processes. In terms of chromogenic substrates, Trinder's reagents such as TOOS, MAOS, DAOS, etc. are compared with similar foreign products, and some indicators have characteristics in low background interference and color stability. They have been applied in various types of in vitro diagnostic kits. For reagent manufacturers who are optimizing biochemical testing projects such as uric acid, kidney function, and blood glucose, the control of impurities in chromogenic substrates and inter batch differences are topics worth discussing on site. In addition, the enzyme preparation project team established by the company since 2024 will also showcase its related products, demonstrating its extension in the upstream raw material direction of diagnostic reagents. Company Strength: Two Bases and Capacity Support Hubei Xindesheng Material Technology Co., Ltd. was registered and established in 2017, formerly known as Wuhan Desheng Biochemical Technology Co., Ltd. established in 2005. The company is headquartered in Guanggu United Science and Technology City, Gedian Development Zone, Ezhou City, Hubei Province. It has two research and development production bases, Gedian (54 acres) and Huanggang (70 acres), with an annual production capacity of 5000 tons for all categories. With the commissioning of the new Huanggang factory, the production capacity of biological buffering agents, carbomers and other products has been further improved, providing more stable supply guarantees for the fields of biomedicine and daily chemical products. These production capacity layouts are the practical basis that customers pay more attention to when evaluating raw material suppliers. On site communication: come with questions, go with ideas During the exhibition, the sales and technical R&D team of Xindesheng will be stationed throughout the entire process. Whether it's confirming product parameters, matching application scenarios, or selecting raw materials for reagent kit development and process scaling, face-to-face communication can be conducted at the booth. For customers who are interested in cooperation, it is recommended to sort out the demand list in advance, such as target testing items, pain points in existing formulas, tolerance range for batch differences, etc. The on-site communication will be more targeted. Analytica China is not only a platform for showcasing products, but also an opportunity for industry colleagues to exchange technology and explore trends. Hubei Xindesheng cordially invites all new and old partners to visit booth N4-4113 to discuss products, applications, and cooperation. We look forward to meeting you in Shanghai, living up to our expectations, and sharing a beautiful journey together!

Protein purification usually consists of multiple steps in series, each with specific requirements for the buffer system. CAPS Buffer has potential applications in chromatography, ultrafiltration, and dialysis due to its buffering capacity in the alkaline range and low tendency towards metal complexation. Understanding its role in the purification process can help design more coherent process plans and reduce sample loss caused by buffer switching. Buffer selection in chromatography steps Ion exchange chromatography is often operated at alkaline pH to negatively charge the target protein and bind it to the anion exchange medium. CAPS can provide stable pH in this range, and its sulfonic acid groups are negatively charged and do not compete with anion exchange media for binding sites. Compared with Tris, CAPS has lower nucleophilicity and is less prone to side reactions with the ligand in the medium. Before use, it is necessary to confirm the stability of the target protein in CAPS buffer to avoid aggregation or precipitation caused by buffer components. Salt and pH synergy in hydrophobic chromatography Hydrophobic chromatography relies on high salt conditions to promote protein binding to the medium, while CAPS itself has a certain ionic strength and can be used as an auxiliary component for salt precipitation. However, it should be noted that the cyclohexyl group of CAPS has hydrophobicity, which may alter the behavior of the hydrophobic regions on the protein surface and affect the binding strength. When developing the method, it is recommended to use CAPS concentration as a variable for screening and observe changes in the retention time and recovery rate of the target protein. Compatibility considerations in affinity chromatography Affinity chromatography is sensitive to buffer components, especially when the ligand is a metal ion or contains chelating structures. The weak metal chelating ability of CAPS may reduce the loading capacity of nickel or cobalt columns, and should be carefully evaluated. For antibody affinity chromatography, CAPS usually does not affect the binding of Protein A or Protein G to antibodies, but if a lower pH is required for the elution step, CAPS is not suitable and needs to be switched to an acidic buffer. PH stability in ultrafiltration and dialysis During the concentration and liquid exchange process, the sample comes into prolonged contact with the membrane material. The adsorption of CAPS buffer on ultrafiltration membrane is low, and the flux decay is relatively slow. During dialysis fluid exchange, the molecular weight of CAPS is relatively small and can freely pass through the dialysis membrane. However, it should be noted that the dialysate also needs to contain CAPS to maintain pH balance, otherwise the sample pH will drift due to buffer dilution. Temperature management during purification process Purification operations are often carried out under cold or low-temperature conditions, and the pH of CAPS varies with temperature. If the buffer solution is adjusted at room temperature and then moved to a cold room for use, the actual pH will shift. It is recommended to adjust the pH and measure it at cold room temperature, or compensate based on pre experimental data after adjusting at room temperature. When the chromatography column operates in a cold chamber, the buffer temperature is consistent with the column temperature, which can reduce pH fluctuations during gradient elution. Connection with other buffering agents In multi-step purification, it is often necessary to switch between different buffering agents. CAPS has good compatibility with commonly used buffering agents such as Tris and phosphate, but attention should be paid to the superposition effect of ion strength and pH when mixing. For example, when switching from Tris buffer to CAPS buffer, if the pH of the two is different, a transition buffer should be used to balance them first, in order to avoid sudden pH changes caused by direct switching and protein precipitation. Summary CAPS can be used as an alkaline buffer in protein purification processes for steps such as chromatography, ultrafiltration, and dialysis. Its low nucleophilicity and weak metal complexation characteristics exhibit mild behavior in most scenarios, but require special evaluation in metal affinity chromatography and hydrophobic chromatography. Through temperature management, buffer connection design, and amplification verification, CAPS can become a reliable buffer choice in the purification process. As a supplier of CAPS buffering agents, Hubei Xindesheng ensures that each batch of CAPS buffering agents has stable performance and a purity of over 99% through its processes and strict quality control system. The company has a professional R&D team that constantly explores and optimizes production processes, improves product quality, and meets increasingly diverse market demands. At the same time, Xindesheng also provides attentive customer service, offering professional technical consultation and solutions to customers.

HEPES, as a commonly used buffering agent in the laboratory, has a direct impact on the final quality of the solution due to the dissolution behavior of its solid form and the details of the preparation process. AR analysis pure grade products meet the basic requirements of conventional analysis and biochemical experiments in terms of purity, but specific steps still need to be taken into account during operation to ensure the full utilization of buffering performance. Mastering the standardized preparation process can help reduce batch differences and extend the effective lifespan of the solution. Characteristics of dissolution behavior in solid form HEPES is usually supplied in the form of white crystalline powder, and its dissolution process in water requires a certain amount of stirring or oscillation assistance. Unlike some inorganic salts, HEPES does not produce significant endothermic or exothermic effects when dissolved, and the temperature change of the solution is relatively small. At room temperature, AR grade HEPES can quickly reach a clear state, but if a high concentration mother liquor is prepared, the dissolution time may be prolonged. It is recommended to use a gradual addition method, stirring while adding to avoid one-time pouring that may cause clumping at the bottom. If the solution becomes slightly turbid after dissolution, the stirring time can be moderately extended and the clarity can be observed. If the turbidity persists, the quality of the raw materials or the purity of the solvent should be considered. Selection of water and containers for preparation When preparing HEPES buffer, the purity of water has a direct impact on the quality of the final solution. AR analysis grade HEPES is suitable for most non cell culture analysis and detection. It is recommended to use distilled water or purified deionized water for preparation, and the conductivity should meet the laboratory's conventional requirements. In terms of containers, glass beakers or polypropylene plastic containers can be used, but it is necessary to ensure that they are cleaned thoroughly and free of residual detergent. Newly purchased containers should be thoroughly rinsed with pure water before use to avoid introducing particulate matter or organic pollutants. For mother liquor that requires long-term storage, it is recommended to use a covered storage bottle and seal it for storage. The sequence and method of pH adjustment HEPES powder itself has acid-base properties, and the initial pH of the solution dissolved in pure water is usually slightly acidic or near neutral, depending on the amount of feed and the amount of dissolved carbon dioxide in water. When adjusting pH, it should be done after HEPES has completely dissolved and the solution temperature has stabilized at room temperature. The commonly used adjustment reagents are sodium hydroxide solution or hydrochloric acid solution, and the acid or base is selected for titration according to the desired target pH. During the adjustment process, a calibrated pH meter should be used for real-time monitoring to avoid relying solely on test strips or colorimetric methods for rough judgments. It should be noted that AR grade products do not contain biological grade impurity control indicators, but their stability performance after pH adjustment meets the requirements of general analytical experiments. Storage conditions and stability observation HEPES solution can be stored for a certain period of time at room temperature, but long-term storage may face problems such as water evaporation, pH drift, or microbial contamination. It is recommended to store the prepared solution in a cool and dark place, avoiding direct sunlight and severe temperature fluctuations. The chemical purity of AR grade products meets the analytical requirements, but no preservatives have been added, so the appearance and pH value of the solution should be checked regularly. If the solution changes color, particles appear, or the pH exceeds the acceptable range, it should not be continued to be used. Packaging and storage is an effective way to reduce pollution and evaporation losses, and the bottle cap should be tightly closed after each use. Common problems and troubleshooting suggestions If incomplete dissolution occurs during the preparation process, it can be checked whether the weighing is too large, the water temperature is too low, or the mixing is insufficient. Increasing the water temperature appropriately or extending the mixing time can usually improve the situation. If there is a rebound or decline after pH adjustment and left for a period of time, it may be due to the solution not being completely balanced or carbon dioxide dissolved in the environment. After adjustment, let it stand for a moment and retest to reduce such deviations. For detection items sensitive to ion strength, accurate weighing and strict control of the volumetric volume are required during preparation to avoid concentration errors from being transmitted to downstream experimental results. As a HEPES buffer manufacturer, Desheng strictly monitors product quality and sets up a quality department to inspect batches of products. Only after the packaging and quality meet the standards can they be sold from the factory. Therefore, Desheng has received unanimous praise from customers.
