Description: The platelet-derived growth factor AA (PDGF-AA) is a member of the PDGF family. The PDGF proteins are derived from four genes (PDGF-A, -B, -C, and -D) that form four disulfide-linked homodimers (PDGF-AA, -BB, -CC, and -DD) and one heterodimer (PDGF-AB). PDGF-AA plays an important role as a mitogen for a number of cell types. Recombinant Mouse PDGF-AA produced in e.coli is a non-glycosylated homodimer of 126 amino acids with a molecular weight of 28.9 kDa.
