Description
- General description: HEPES has been described as one of the best all-purpose buffers available for biological research.[1] 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.[2]
- Application: HEPES has been used:In the novel vesicle-budding protocol as a component in stock solution and buffer solutions[3]As a component in intracellular solution for the preparation of brain-slice recording[4]As a component of wash buffer, elution buffer and desalting buffer during affinity protein purification[5]To maintain the pH at 7 in thermal denaturation assay of purified protein[5]In isocratic elution of protein using gel filtration[5]Along with NaCl in sample preparation for EPR (Electron Paramagnetic Resonance) spectroscopy[5]
