Other Notes
One of the best general purpose buffers available for biological research. Has been used to advantage in tissue culture, oxidative phosphorylation, protein synthesis with cell-free bacterial systems, photophosphorylation, CO2 fixation1,2; Suitable buffer for TEM studies (Transmission Electron Microscopy) as it does not affect metal substrates3; Recommended buffer for the glutamate binding assay, prevents binding to non-receptor materials4.
Easily compare specifications for HEPES products with the HEPES specification table.
