HEPES, FREE ACID is supplied by TM MEDIA.HEPES is a buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is a zwitterionic, piperazinic buffer that is useful for a pH range of 6.8 8.2. HEPES lacks the ability to form a significant complex with most metal ions and is recommended for use as a non-coordinating buffer in solutions with metal ions. HEPES-free acid can be mixed with HEPES sodium salt to achieve the desired pH. Alternatively, HEPES-free acid can be titrated with NaOH or KOH to achieve the desired pH.
