Description

CHAPS, a derivative of Cholic acid, is a zwitterionic detergent for solubilizing membrane proteins. CHAPS is used for stabilization of various protein-DNA complexes and can retain biochemical activity of proteins in solution[1][2].

In Vitro

CHAPS (0.5 %) is able to stabilize complexes between DNA and DNA-binding factors such as AP-1, SPI, GATA-1 and α-regulated factor ISGF3, and retains their biochemical activity[2].
CHAPS can prevent dissociation of mononucleosomes diluted to sub-nanomolar concentrations[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
