Product Description

Potassium Phosphate Dibasic Trihydrate

Application Notes

Potassium phosphate typically used as a component for a wide variety of media used in the culture of microorganisms, as a component in phosphate buffered saline (PBS). In addition to helping maintain pH, it supplies essential phosphate. The use of high concentrations of potassium phosphate in the immobilization of affinity ligands onto epoxide-activated stationary phases has been reviewed. A two-phase system of aqueous potassium phosphate and poly(ethylene glycol) for the isolation of E. coli β-galactosidase and β-galactosidase fusion proteins has been published. The quantitation of nonionic surfactants in buffered solutions using strong cation and anion exchange HPLC guard columns and potassium phosphate solution has been investigated.
