Buffers, Detergents & Protease Inhibitors

Buffers, detergents and protease inhibitors are basic reagents for preparing, lysing and stabilizing biological samples. Zwitterionic Good's buffers such as HEPES, MOPS, PIPES and MES hold pH steady in the physiological range, while Tris serves electrophoresis and general use. Detergents such as CHAPS, polysorbate 20 and sodium dodecyl sulfate (SDS) solubilize membranes and proteins. Dithiothreitol (DTT) keeps thiol groups reduced, and ethylenediaminetetraacetic acid (EDTA) chelates divalent metal ions. Protease inhibitors such as leupeptin, aprotinin, pepstatin A and E-64, with the phosphatase inhibitor sodium orthovanadate, protect proteins in cell lysates.
