Specificity
This antibody recognises human PDGF-BB (Platelet derived growth factor B chain), a disulphide-linked beta-chain homodimer and member of the PDGF family, released from platelet alpha-granules following trauma/platelet activation.Naturally occurring active forms of PDGF exist as dimers of two alpha chains (AA), two beta chains (BB), or a combination of both chains (AB), all of which signal through the high-affinity PDGF-Ralpha receptor, and the latter two of which can also signal through the PDGF-Rbeta receptor. PDGFs are potent mitogens for a variety of cells including those of the connective tissue, bone and cartilage, blood and smooth muscle cells, and are involved in several biological processes including chemotaxis, hyperplasia and embryonic neurogenesis.The expression of PDGF-BB is associated with autocrine growth stimulation and the formation of various tumour types.
