PIPES buffer: the core "protector" of microtubule protein purification experiments

This article analyzes the key role of PIPES in the purification of microtubule proteins by phosphocellulose chromatography: firstly, it stabilizes the pH environment and maintains the bottom line of microtubule protein activity; The second is to chelate interfering ions and clear purification and separation barriers. At the same time, it is pointed out that the use should be avoided for redox experiments and high concentrations for cation exchange chromatography. High quality PIPES raw materials are the foundation of successful experiments. Hubei Xindesheng has been focusing on biological buffering agents for nearly 20 years, providing high-purity and highly stable PIPES products.

Glucose Dehydrogenase (GDH): Process Optimization and Application of Sensor Core Enzyme

This article introduces the key application of glucose dehydrogenase (GDH) in implantable sensors: the original GDH needs to undergo a dedicated modification process to adapt to the sensor. The core process includes three steps: molecular unfolding activation sites, electron mediator modification to improve transfer efficiency, and cross-linking fixation to ensure the stability of the sensing membrane. New Desheng provides high-quality GDH raw materials to assist in sensor research and development

How to ensure the high purity of TRIS reagents: strictly control every step from the source to the process

How to ensure the high purity of TRIS reagents: strictly control every step from the source to the process

The purity of TRIS directly affects the accuracy of experiments and the stability of reagents. High purity TRIS requires controlling the quality of raw materials from the source to prevent the introduction of heavy metals and organic impurities; By optimizing the synthesis process to reduce by-products, and combining multi-stage purification such as recrystallization and ultrafiltration to deeply remove impurities, the entire production process is carried out in a clean environment to prevent secondary pollution. Hubei Xindesheng has established a full process quality control system to ensure that TRIS purity exceeds industry standards and is suitable for various precision scenarios such as molecular biology and IVD reagents.

Glucose dehydrogenase (GDH): a core enzyme for biosensing analysis

Glucose dehydrogenase (GDH) is the core enzyme preparation of glucose sensors, which can specifically catalyze the glucose dehydrogenation reaction, efficiently complete the precise conversion of concentration to electrochemical signals, and is not affected by oxygen interference. It is suitable for multiple scenarios such as implantable, portable, and dual analyte synchronous monitoring. Hubei Xindesheng independently develops high activity and high stability GDH, with performance comparable to imported standards, supporting customized solutions, and helping domestic substitution and industry cost reduction and efficiency improvement.

Lactate dehydrogenase (LDH): a key support for the diagnosis of myocardial infarction

Lactate dehydrogenase (LDH): a key support for the diagnosis of myocardial infarction

The lactate dehydrogenase (LDH) diagnostic reagent, based on the principle of enzyme catalysis, achieves accurate quantification and is a key tool for the diagnosis and treatment of myocardial infarction. It not only enhances specificity through the ratio of isoenzymes, but also fills the diagnostic gap 24 hours after onset. Reagents need to be operated strictly and standardized to avoid hemolysis interference. The stable supply of high-quality diagnostic enzyme raw materials is the core foundation for ensuring the clinical accuracy and reliability of reagents.
