HEPES (2-[4-(2-hydroxyethyl)-1-piperazinyl]ethanesulphonic acid) free acid ≥99%, high purity
HEPES (2-[4-(2-hydroxyethyl)-1-piperazinyl]ethanesulphonic acid)
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.
