CAPS Buffer 0.5M, pH 10.5

Synonym: 3-(Cyclohexylamino)-1-propanesulfonic acid, N-Cyclohexyl-3-aminopropanesulfonic acid

CAPS buffer is a zwitterionic buffer widely used in Western and immunoblotting experiments as well as protein sequencing and identification.
Used in the electrotransfer of proteins to PVDF or nitrocellulose membranes.
The high pH of this buffer makes it useful for the transfer of proteins with a pI > 8.5.
CAPS buffer has very low metal-binding constants and are therefore particularly suited to investigate metal-dependent enzymes.
CAPS is 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.
