Description
β-
Glycerophosphate is a protein phosphatase inhibitor that acts as a phosphate group donor in matrix mineralization studies. It promotes bone matrix mineralization when delivered to osteoblasts by providing a source of phosphate ions. β-
Glycerophosphate (10 mM) accelerates calcification of cultured vascular smooth muscle cells through an alkaline phosphatase-
related mechanism.
Chemical Properties
Solid
Uses
Sodium β-glycerophosphate pentahydrate is used as a phosphatase inhibitor. It promotes bone matrix mineralization while delivering to osteoblasts by providing a source of phosphate ions. It is used in the development of hydrogels and scaffolds, which finds applications in tissue engineering and cell growth. It is used as an additive in isolation mediums by providing phosphate ions to isolate. It is utilized to promote mineralization in vitro by modulating bone cell metabolic activity.
Uses
β-Glycerol Phosphate was shown to have promoted mineralization in vitro by modulating bone cell metabolic activity and/or serving as a local source of inorganic phosphate ions.
General Description
A phosphate group donor in matrix mineralization studies. Accelerates calcification in vascular smooth muscle cells. Also acts as a protein phosphatase inhibitor.
Biochem/physiol Actions
Beta-Glycerophosphate is a classical serine-threonine phosphatase inhibitor used in kinase reaction buffers. BGP is often used in combination with other phosphatase/protease inhibitors for broad spectrum inhibition. It functions as an organic phosphate donor and has been used in culture media for mesenchymal stem cell differentiation to osteoblast-type cells. BGP is also used to buffer M17 media for Lactococcus culture in recombinant protein expression
Purification Methods
Crystallise it from water. [Attwood et al. Biochem J 253 389 1988, Beilstein 1 IV 2766.]
