HEPES 1M Solution, Sterile Filtered, 2 x 500ML

HEPES is a zwitterionic organic buffering agent. It is stable, water soluble and does not react with divalent cations. It has a pKa of 7.5 at 37deg C and offers an optimal buffering range of pH 6.8 - 8.2. It maintains the physiological pH despite changes in the carbon dioxide concentrations which take place due to cellular metabolism. HEPES is widely used in cell culture media to maintain the pH levels of basal media. Unlike the bicarbonate buffers which require CO2, HEPES containing media do not need CO2 atmosphere for buffering. HEPES is better than bicarbonate buffer in controlling the pH of the media in cell culture. HEPES is generally used at a concentration of 10mM to 25mM for cell culture application. TCL021 is 1M HEPES solution prepared in sterile tissue culture grade water. Appearance: Colorless, clear solution Sterility: No bacterial or fungal growth is observed after 14 days of incubation, as per USP specification Cultural Response: Growth Promotion Test
