Caps needs better purity when it is used as biological buffer. Generally, it needs analytical purity. When it is used in industry, the purity requirement is relatively low, but it also needs different treatment for different applications.
3-cyclohexylaminopropane sulfonic acid (CAPS) is mainly used in biochemical diagnostic kits, DNA / RNA extraction kits and PCR diagnostic kits, and as a buffer for enzyme chemistry and HPLC separation of basic drugs. 3-cyclohexylaminopropane sulfonic acid (CAPS) can also support alkaline phosphatase activity and inhibit the growth of Aeromonas at pH 10.5, and can be dissolved in deionized water and adjusted to pH 11.0 for purification of fibronectin.
In the field of capillary electrophoresis analysis, 3-cyclohexylaminopropane sulfonic acid (CAPS) is used to prepare the running buffer (background electrolyte solution) in capillary electrophoresis. As the end electrolyte, it can realize the online enrichment and separation of 2-nitrobenzoic acid and 3-nitrobenzoic acid by electric pressurization.
The results showed that the hybridization products of caps and 3 - (2-amino) - cyclopropyl sulfonate (3-cyclopropyl) - 3-amino sulfonate (3-cyclopropyl) could be used to improve the specific yield of nucleic acid The yield of the target hybrid product was determined. It has important value in the identification of specific pathogens, the diagnosis of genetic diseases and the analysis of gene sequences.
3-cyclohexylaminopropane sulfonic acid (CAPS) is also an important hydrophilic modifier. It can react with polyisocyanate under very mild reaction conditions and in the presence of suitable neutralizing amine, so as to prepare polyisocyanate products which can be emulsified into fine dispersion form in water and have stable storage.
Desheng began to develop and produce biological buffer, blood collection additive, chemiluminescence reagent, color reagent, etc. since 2005. Caps is a kind of biological buffer with purity > 99% and stable process. Tris, bicine and HEPES are the company's key R & D products. Welcome friends to inquire.
