CAPS Buffer 0.5M, pH 9.5

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.
