Application

HEPES has been used:
  • In the novel vesicle-budding protocol as a component in stock solution and buffer solutions
  • As a component in intracellular solution for the preparation of brain-slice recording
  • As a component of wash buffer, elution buffer and desalting buffer during affinity protein purification
  • To maintain the pH at 7 in thermal denaturation assay of purified protein
  • In isocratic elution of protein using gel filtration
  • Along with NaCl in sample preparation for EPR (Electron Paramagnetic Resonance) spectroscopy

General description

HEPES has been described as one of the best all-purpose buffers available for biological research. At biological pH, the molecule is zwitterionic, and is effective as a buffer at pH 6.8 to 8.2. HEPES has been used in a wide variety of applications, including tissue culture. It is commonly used to buffer cell culture media in air. HEPES finds its usage in in vitro experiments on Mg.
