3.Product Feature And Application
3-cyclohexylamino propanesulfonic acid or CAPS, which CAS number is 1135-40-6. As a fine chemical intermediate; In medicine, it is used Biological buffer; Buffer for enzyme chemistry and HPLC separation of alkaline drugs.
Can be used in many fields. Such as,
● in nucleic acid extraction
It can prepare solutions for nucleic acid hybridization with 3 - [(3-choleamidopropyl) dimethylammonium] - 1-propanesulfonate (chaps), 3 - (cyclohexylamino) - 2-hydroxy-1-propanesulfonate (capso), and 2 - (cyclohexylamino) ethanesulfonate (ches). It can reduce the yield of nonspecific hybrids and improve the specificity of nucleic acid hybridization, while maintaining the yield of target hybridization products. It is of great value in the identification of specific pathogens, the diagnosis of genetic diseases, the analysis of gene sequences and so on.
● high quality waterborne two-component polyurethane coating
3-cyclohexylamino propanesulfonic acid or CAPS can be used in various environment-friendly high-quality waterborne two-component polyurethane coatings. It can coexist with resins containing active genes (hydroxyl, carboxyl, amine, epoxy, etc.) for a long time at room temperature. The application of caps in coatings is widely used in water-based coatings market.
● in capillary electrophoresis analysis
3-cyclohexylamino propanesulfonic acid or CAPS can be used to prepare the running buffer (background electrolyte solution) in capillary electrophoresis. As the terminal electrolyte, caps can realize the on-line enrichment and separation of 2-nitrobenzoic acid and 3-nitrobenzoic acid by electric pressurization. Caps buffer is suitable for electrophoresis buffer with high amount of protein (greater than 20kD). If it is a low molecular weight protein imprinting experiment, Tris + glycine protein sequencing is generally used to exclude glycine, and tris Tricine + EDTA is used.
● in the kit
3-cyclohexylamino propanesulfonic acid or CAPS can also be used as biochemical diagnostic kit, dnavrna extraction kit and PCR diagnostic kit as buffer for enzymatic chemical HPLC separation of alkaline drugs. Caps is widely used in the membrane transfer process of protein sequencing. As Western blot buffer or membrane transfer buffer, caps can also support alkaline phosphatase activity and inhibit the growth of Aeromonas at pH 105. It is dissolved in deionized water and used for the purification of fibronectin after adjusting pH to 110. In addition, caps is also used as cationic cross stripping welding materials, air conditioning equipment and manufacturing raw materials. It can also be used in the manufacture of fireworks, analytical reagent, hot dressing industry, air conditioning, fireworks, dry battery and other applications.
