PDGF, BB Homodimer, Human, Recombinant, E. coli

Recombinant, human platelet-derived growth factor (disulfide-linked dimer of two 109 amino acid B-chain monomers) expressed in E. coli. Shown to be a potent chemoattractant for neutrophils, mesenchymal, and mononuclear cells. PDGF represents one of the major mitogens present in platelets. It exerts its effects by binding to specific high-affinity dimeric receptor tyrosine kinases. Material has the same amino acid sequence as mature human PDGF-B. Two distinct PDGF receptors have been identified: the PDGFα receptor, which binds to all three forms of PDGF, and the PDGFβ receptor, which can bind only PDGF-BB and PDGF-AB.

ED₅₀ = 1-5 ng/ml as determined by the dose dependent proliferation of BALB/c 3T3 cells

Toxicity: Standard Handling (A)
