Platelet Derived Growth Factor (PDGF) is a potent mitogen for a wide range of cell types including fibroblasts, smooth muscle and connective tissue. PDGF, which is composed of a dimer of two chains termed the A chain and B chain, can be present as AA or BB homodimers or as an AB heterodimer.||Source: |Recombinant protein corresponding to human PDGF-BB, a disulfide-linked homodimer of two B chains, 218 total amino acids, expressed in E. coli.||Molecular Weight: 24.3kD||Biological Activity: |The ED50 as determined by the dose-dependent stimulation of BALB/c 3T3 cells proliferation is < 1ng/ml||Endotoxin: ≤1EU/ug (LAL)||Applications: |Suitable for use in ELISA. Other applications not tested.||Recommended Dilution:|Optimal dilutions to be determined by the researcher.||Storage and Stability:|Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile PBS. Aliquot and store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
