Product Description
HEPES hemisodium salt may be used in the preparation of HEPES buffer, which is one of the best all-purpose buffers available for use in biological research. The molecule is zwitterionic at most biological pHs and is most effective as a buffer at pH 6.8 to 8.2. May be used in isoelectric focusing applications and as a buffer in the quantitative and selective measurement of antigen-antibody reactions.
