The Uses of Potassium phosphate tribasic

Potassium phosphate tribasic is a reagent with a very high buffering capacity. It is widely used in molecular biology, biochemistry, and chromatography, used for the extraction of keratohyalin protein from bovine tissue, to study the effects of freezing and thawing on the stability of proteins sensitive to conformational changes. It is used as a food additive for its properties as an emulsifier, foaming agent, and whipping agent.

The Uses of Potassium phosphate tribasic

It is used as a buffering agent.

The Uses of Potassium phosphate tribasic

Potassium phosphate tribasic has been used:

• in lysis buffer for the isolation of protein from Gram positive bacteria
• as a reagent for the scalable synthesis and post-modification of NU-1000 (mesoporous metal-organic framework)
• as a reagent for the plasma membrane preparation of Lilium davidii or Oryza sativa with high purity

What are the applications of Application

Potassium phosphate tribasic is a reagent with very high buffering capacity widely used in molecular biology

Preparation

The tribasic salt is produced by complete neutralization of phosphoric acid with potassium hydroxide, followed by evaporation and crystallization:H₃PO₄+ 3KOH →K₃PO₄+ 3H₂O.
