HEPES is a general purpose buffer available for biological research.
Has been used to advantage in tissue culture, oxidative phosphorylation, protein synthesis with cell-free bacterial systems, photophosphorylation and CO₂ fixation. Suitable buffer for TEM studies (Transmission Electron Microscopy) as it does not affect metal substrates. Recommended buffer for glutamate binding assays, preventing binding to non receptor materials.
