3-[(3-Cholamidopropyl)dimethylammonio]-1-propansulfonat (CHAPS) zwitterionisches Detergens, Pierce™
Lieferant: Thermo Fisher Scientific
Synonyms:
CHAPS
Thermo Scientific CHAPS is a zwitterionic detergent that is especially well suited for protecting the native state of proteins.
- Versatile zwitterionic detergent
- Provides mild but effective lysis of cultured mammalian cells
- Nondenaturing and generally does not inactivate protein functions
- Can be removed from solution by dialysis
- Commonly used for isoelectric focusing (IEF) and 2D electrophoresis
CHAPS is sulfobetaine derivative of cholic acid
CHAPS has been successfully used to solubilize intrinsic membrane proteins and receptors and maintain the functional capability of the protein of interest. CHAPS has also been used in combination with nonionic detergents such as NP-40 for nondenaturing gel electrophoresis applications. CHAPS has largely replaced NP-40 in isoelectric focusing (IEF) applications, where it prevents streaking in certain pH ranges. The neutral charge of CHAPS and its disaggregating properties are believed to be responsible for the improvement.
