Used to formulate CAPS buffer, a zwitterionic buffer 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 electro transfer 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. 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.
