Used extensively as a buffering agent in biological and biochemical research to maintain stable pH levels in cell cultures and enzyme studies. It is particularly effective in maintaining physiological pH ranges, making it ideal for experiments involving live cells or tissues. Commonly employed in molecular biology techniques such as electrophoresis, chromatography, and protein purification. Its low toxicity and minimal interaction with biological systems make it a preferred choice for in vitro studies. Additionally, it is used in the preparation of media for bacterial and mammalian cell cultures, ensuring optimal growth conditions.
