CHAPS

Cholamidopropyldimethylammonio-1-propane-sulfonate

Zwitterionic Detergent

White solid. Has all of the advantages of sulfobetaine-containing

detergents, hydrophobic, bile salt and anionic detergents in a

single molecule. Has small micellar molecular weight and high

CMC and can be removed from protein solutions with a detergent

removing gel or by dialysis across a membrane.

Purity >98% by HPLC. Conductivity <25 umhos in a 10% solution.

M.W. 614.9 CAS 75621-03-3. C₃₂H₅₈N₂O₇S

CHAPSO

Cholamidoropyldimethylammonio-2-hydroxy-1-propanesulfonate

Zwitterionic Detergent

White solid. Higher solubility than Chaps. Solubilizes membrane

bound proteins in their native state. Solubilizes opiate receptor

to a state exhibiting reversible binding of opiates.

Purity >98% by TLC. Conductivity <50 umhos for 10% solution.
