White powder




Cool Dry Place



Chemical Properties:

White crystalline powder


  1. Non-toxic to cell. It is used as a hydrogen ion buffer, which can control the constant pH range for long term. The concentration is 10-50mmol/L. Generally, 20mmol/LHEPES in nutrient solution can get buffer ability.
  2. Biological buffer.
  3. HEPES (4-hydroxyethyl piperazine ethanesulfonic acid) is a non-ionic amphoteric buffer with high polarity. It is inert to a variety of chemical reagents and enzymes, does not participate in and interfere with the process of biochemical reaction, and has no inhibitory effect on enzyme chemical reaction. Therefore, it can be specially used for the research of organelles, highly variable and pH sensitive proteins and enzymes.
  4. HEPES is used as biochemical reagent
