Growth factor that plays an essential role in the regulation of embryonic development, cell proliferation, cell migration, survival and chemotaxis. Potent mitogen for cells of mesenchymal origin. Required for normal proliferation and recruitment of pericytes and vascular smooth muscle cells in the central nervous system, skin, lung, heart and placenta. Required for normal blood vessel development, and for normal development of kidney glomeruli. Plays an important role in wound healing. Signaling is modulated by the formation of heterodimers with PDGFA. Recombinant protein corresponding to aa82-190 from mouse Platelet-derived growth factor subunit B, fused to 6X His-Tag at C-terminal, expressed in E.coli. Molecular Weight: ~13.4kD Biological Activity: The ED50 as determined in a cell proliferation assay using BALB/c 3T3 cells is less than 40ng/ml.
