PDGF-BB (human), animal free recombinant

Product Description: PDGFs are dimers linked by disulfide bonds, composed of two 12.0-13.5 kDa polypeptide chains known as PDGF-A and PDGF-B. Among the three naturally occurring PDGFs (PDGF-AA, PDGF-BB, and PDGF-AB), they act as potent mitogens for various cell types such as smooth muscle cells, connective tissue cells, bone and cartilage cells, and certain blood cells. These growth factors are stored in platelet alpha-granules and are released during platelet activation, contributing to processes like hyperplasia, chemotaxis, embryonic neuron development, and respiratory tubule epithelial cell development. PDGFs interact with two distinct signaling receptors: PDGFR-alpha, a high-affinity receptor for all three PDGF forms, and PDGFR-beta, which specifically interacts with PDGF-BB and PDGF-AB. Recombinant Human PDGF-BB is a 24.3 kDa disulfide-linked homodimer consisting of two beta chains, totaling 218 amino acids. . Amino acid sequence: SLGSLTIAEP AMIAECKTRT EVFEISRRLI DRTNANFLVW PPCVEVQRCS GCCNNRNVQC RPTQVQLRPV QVRKIEIVRK KPIFKKATVT LEDHLACKCE TVAAARPVT. Endotoxin concentration: <0.1 EU/µg. Activity: Determined by the dose-dependent stimulation of the proliferation of Balb/c 3T3 cells. The expected ED50 for this effect is 1.0-3.0 ng/ml. Contains no preservative. Protein function: 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 (PubMed:26599395). 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. [The UniProt Consortium]
