AG Scientific Inc CHAPS, High Purity, 5 G
CHAPS is a zwitterionic detergent that is widely used in the protein purification process. As part of this class of detergents, CHAPS contains both a positive and a negative group, but does not have a net overall charge. CHAPS has a relatively low biomembrane affinity, but is effective in inducing hemolysis and protein solubilization within specific concentration ranges. CHAPS is classified as a non-denaturing surfactant with a critical micelle concentration of 6-10mM.ApplicationsIn the laboratory, CHAPS and other zwitterionic detergents can be used for inducing cell lysis prior to protein isolation.CAS Number: 75621-03-03Molecular Weight: 614.9Chemical Formula: C32H58N2O7SSolubility: Soluble in DMSO or DMFStorage Temperature: Room TemperatureResearch or further manufacturing use only, not for food or drug use.
