Corning 100 Ml Hepes, Liquid 1m Solution (238.3 Mg/Ml)

Corning Technical Advantage: Product manufactured under industry-leading standards for low endotoxin content and superior results HEPES (N-2-hydroxyethylpiperazine-N#39;-2-ethanesulphonic acid) provides an alternative to the use of bicarbonate for buffering because it does not require elEVAted levels of CO2. Unlike the low pKa of bicarbonate, HEPES has a pKa of 7.66 making it a much stronger buffer in the pH 7.2-7.6 range than bicarbonate buffer. Potential disadvantages of HEPES include toxicity over 100 mM and lack of nutritive value to the cell. The recommended working concentration is 10-25 mM.
