HEPES is used as a hydrogen ion buffer, which can control the constant pH range for long term. The concentration is 10-50mmol/L. Generally, 20mmol/LHEPES in nutrient solution can get buffer ability.
HEPES is a biological buffer. It may be used in isoelectric focusing applications and as a buffer in the quantitative and selective measurement of antigen-antibody reactions. HEPES is reportedly superior to NaHCO3 in controlling pH in tissue and organ culture. HEPES is not recommended for use with the Folin-Ciocalteu protein assay.
HEPES 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.
