Application:

HEPES (CAS: 7365-45-9) is common buffer for biological sciences, particularly used in cell culture to maintain physiological pH. It acts a buffering component, which is used in the preparation of buffers. It is described as one of the best all-purpose buffers available for use in biological research. HEPES has been used as a component of: Hank′s balanced salt solution, Dulbecco′s modified eagle′s medium and no-glucose DMEM, which are used for the preparation of tissue slices. Buffers used in localized conductance measurements on the basolateral side of culture inserts to examine cation selectivity.
