Description

General description

CHAPS is a non-denaturing, zwitterionic sulfobetaine detergent. It is mild and solubilizes membrane proteins and receptors. It is useful for breaking protein-protein interactions. It is a derivative of the naturally occurring bile salts. It has small micellar molecular weight (6,150) and high critical micellar concentration (6 - 10 mM) allowing it to be removed from samples by dialysis.

Application

0.2 w/v of CHAPS has been used to remove cerebral endothelium by brain perfusion. 2% (w/v) CHAPS has been used as rehydration buffer along with Thiourea and Urea in protein extraction. 10 mM CHAPS has been used along with 0.15 M NaCl, Tris–Cl, pH 7.6, EDTA as lysis buffer in Western Blot analysis. CHAPS has been used as hybridization buffer in in-situ hybridization method of immature mammalian CNS.

Packaging
