Applications of HEPES buffer

Since the growth and metabolism of cells in culture can cause dramatic environmental pH changes of the culture media, therefore, to maintain an environment in which cells could be stably cultured, it is necessary to add an appropriate amount of certain biological buffer(s) to the culture media. However, there are so many biological buffers and alternatives available for cell culture on the market, why HEPES? In general, the optimal culture environment for most cells is pH 7.2-pH 7.4 ^[1][2], and the buffering range of HEPES falls exactly in pH 6.8-pH 8.2, which is favorable for cell culture. Compared with other buffers such as PBS (phosphate buffered saline) and TRIS, HEPES has higher stability in maintaining the pH values of the cell culture media^[3][4][5], that’s also the reason why HEPES is widely used in cell culture , tissue culture, protein purification and extraction, immunoprecipitation, cell lysis, live cell imaging and other biological/biochemical researches.
