Product Code: HEPE-5201

Suitable for use in biological and biotech chemical process applications from R&D through scale production.

HEPES is a zwitterionic buffer used to maintain pH of media used in cell cultures. It is one of Good’s buffers that has a pKa value similar to its pH value, making it an ideal buffer for pH maintenance. A known limitation is its interference with the Folin protein assay. This buffer can form radicals, so it is not suitable for redox studies. HEPES is a Good’s buffer because it has low UV absorptivity, minimal reactivity, stable pH and is soluble in water.
