Application

β-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.
β-glycerophosphate is used in homegenization solutions for muscles extracts following fixation.
Initiates differentiation of bone-marrow-derived stem cells embedded in a natural collagen/chitosan gel designed for tissue engineering.

Quality

Low inorganic phosphate content. Mixtures of α- and β-glycerophosphate have historically been used in microbiological media but high levels of inorganic (free) phosphate has been associated with the irregular growth of bacteria and unwanted precipitates.

Developing methods for regenerating bones and uncovering the molecular mechanism underlying bone formation have great significance to human health. In the last decade, people have been using adipose-derived stem cells (ADSCs), that are capable of multilineage differentiation, to reconstruct defected
