Potassium Phosphate Dibasic Trihydrate, MP Biomedicals™

Description

Used as a component for a wide variety of media used in the culture of microorganisms and in phosphate buffered saline (PBS). Potassium Phosphate Dibasic Trihydrate, MP Biomedicals is a reagent with high buffering capacity. In addition to helping maintain

Potassium phosphate occurs in several forms: monobasic, dibasic and tribasic. Most pH neutral potassium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH.

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.
