Biological buffering agents play an important role in biochemical research, in vitro diagnosis, and other fields. The CAPSO introduced in this article is a commonly used and important buffering agent. The full Chinese name of CAPSO is 3- (cyclohexylamine) -2-hydroxy-1-propanesulfonic acid, CAS73463-39-5, which appears as a white powder. CAPSO is soluble in water, with a pH buffer range of 8.9-10.3 and a pKa value of 9.6 at 25 ° C. CAPSO is commonly used in immunoblotting and immunoprecipitation experiments, and is widely used in enzymatic reactions and the preparation of detection reagents. Patent CN110488000A describes that CAPSO is used to prepare lysis solutions for extracting membrane proteins. As a buffer, CAPSO can prevent significant pH changes, maintain ion strength within physiological ranges, and prevent proteins from binding with other ions to form insoluble products. CAPSO, as a biological buffer in some enzyme detection reagents, can provide a stable and suitable pH environment for enzymatic reactions. In addition, CAPSO biological buffer can also provide a good storage environment for reagents, which is conducive to stable and effective preservation of reagents. According to publicly available literature, CAPSO can be used in creatine kinase detection kits, aspartate aminotransferase detection kits, and leucine aminopeptidase detection kits, which is of great significance for the prevention and treatment of diseases such as liver disease and myocarditis. Desheng Technology is a new technology enterprise that integrates research and development, production, and sales, with products such as "in vitro diagnostic reagent raw materials", "blood collection additives", "biological buffering agents", and "chemiluminescent reagents" as its main focus. Its main product, biological buffer, is a class of fine chemicals with specialized characteristics, which do not participate in or interfere with biochemical processes. In addition to CAPSO, its advantageous products also include TRIS, HEPES, BICINE, PIPES, TRIS-HCL, MOPS, CAPS, etc. It has a wide range of applications in life science research, in vitro diagnosis, biopharmaceuticals, biological beauty, coatings and paints, and its product quality is recognized and trusted by customers in various industries.
