3-Cyclohexylaminopropanesulfonic Acid Chemical Properties,Usage,Production

Chemical Properties

White/clear crystalline powder

Description

3-Cyclohexylaminopropanesulfonic Acid, also known as 3-(Cyclohexylamino)-1-propanesulfonic acid (CHAPS) or N-Cyclohexyl-3-aminopropanesulfonic acid, is a detergent with a high affinity for basic proteins that can be used to extract these proteins from biological samples and solubilize them. CHAPS is a type of ampholyte, which means it has both anionic and cationic groups.

Uses

3-Cyclohexylaminopropanesulfonic Acid buffer salt is used to formulate CAPS buffer, a zwitterionic buffer that is useful in the range of pH 7.9-11.1. CAPS buffer is widely used in Western and immunoblotting experiments as well as protein sequencing and identification. Used in the electrotransfer of proteins to PVDF (sc-3723) or nitrocellulose membranes (sc-3718, sc-3724). The high pH of this buffer makes it useful for the transfer of proteins with a pI > 8.5. CAPS is not one of the original Good's buffers, although it has a similar structure to the other propanesulfonic acids and was selected as a highly water soluble buffering reagent with an optimum buffering pH of 10.4 and minimal reactivity with enzymes or proteins, minimal salt effects. It is a biological buffer.

Definition

ChEBI: Cyclohexylaminopropanesulfonic acid is an amine.
