PIPES Sesquisodium Salt (CAS: 100037-69-2) 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. PIPES 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. PIPES has wide variety of applications and is commonly used in cell culture media, in protein crystallization, as a running buffer in gel electrophoresis, and as an eluent in isoelectric focusing and chromatography. This buffer is capable of forming radicals and is therefore not suitable for redox reactions. It is suitable for use in the bicinchoninic acid (BCA) assay.
