Beschreibung

Allgemeine Beschreibung

Potassium phosphate monobasic (KH₂PO₄), also known as monopotassium phosphate(MKP), is a soluble salt. It serves as a source of phosphorus and potassium. KH₂PO₄ is an essential component of potassium phosphate buffer, which is utilized in aqueous two-phase systems (ATPS) that are often used in the purification of lipases.

Anwendung

Potassium phosphate monobasic buffer has been used as a component of the mobile phase in high-performance liquid chromatography (HPLC).

Biochem./physiol. Wirkung

Potassium phosphate monobasic (MKP) is a commonly used buffering agent in biochemical and biological applications. It is used as a component of the buffer system in electrophoresis for the separation of biomolecules.
