Hepes 250g (PH.EUR., USP)LRE-S-LC-1007-1
HEPES (4-(2-Hydroxyethyl)piperazine-1-ethane-sulfonic acid) has been described as 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 6.0 to 8.5. May be used in isoelectric focusing applications and as a buffer in the quantitative and selective measurement of antigen-antibody reactions. HEPES has no nutritional benefit to cells. The level of HEPES in cell culture media may vary from 10mM to 25mM.
Hepes has high solubility and is membrane impermeable. It has limited effect on biochemical reactions and is chemically and enzymatically stable.
