HEPES Buffer 1M

HEPES is a zwitterionic organic buffer that is also used to maintain physiological pH of cell culture media. HEPES is recommended when the cell culture system is very sensitive, increasing the buffering capacity and stabilizing the pH within the range of 7.2 to 7.6, and is not dependent on CO₂ levels.

Overview

HEPES is widely used in many biochemical reactions and as a buffering agent in some cell culture media. HEPES has no nutritional benefit to cells. It is added to the media solely for extra buffering capacity when cell culture requires extended periods of manipulation outside of a CO₂ incubator.
