, HEPES free acid
HEPES-2-[4-(2-Hydroxyethyl)-1-piperazinyl]-ethanesulfonic acid free acid, high purity
HEPES (4-(2-Hydroxyethyl)piperazin-1-ylethanesulphonic acid)
One of the best general-purpose buffers for biological research. Excellent for 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 the glutamate binding assay, prevents binding to non-receptor materials.
