CAPS (N-cyclohexyl-3-aminopropanesulfonic 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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
