概要
Platelet-derived growth factor (PDGF) is a dimeric glycoprotein consisting of two disulfide bridge-stabilized polypeptide chains, A and B, which are assembled as heterodimers (PDGF-AB) or homodimers (PDGF-AA and PDGF-BB) (Fretto et al.; Westermark & Heldin). PDGF signals through the receptor tyrosine kinases PDGFRalpha and PDGFRbeta. PDGF-induced migration has been shown to involve MEK/ERK, EGFR, Src, and PI3K/Akt signaling pathways (Kim et al.). PDGF is a potent mitogen for cells of mesenchymal origin- like fibroblasts, glial cells, and vascular smooth muscle cells. PDGF has been implicated in pathogenesis of atherosclerosis, glomerulonephritis, cancer, and in the contraction of vascular smooth muscle cells of rat aortic tissues (Fretto et al.; Sachinidis et al.). It has been shown that PDGF-AB together with 5-Azacytidine (Catalog #72012) induce the conversion of mature bone and fat cells into tissue-regenerative multipotent stem cells (Chandrakanthan et al.). This product is animal component-free.

Data
(A) The biological activity of Human Recombinant PDGF-AB, ACF was tested by its ability to promote the proliferation of NR6R-3T3 cells. Cell proliferation was measured after 46 hours in culture using a fluorometric assay method. The EC50 is defined as the effective concentration of the growth factor at which cell proliferation is at 50% of maximum. The EC50 in the example above is 12.9 ng/mL. (B) 1 μg of Human Recombinant PDGF-AB, ACF was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining. Human Recombinant PDGF-AB, ACF has a predicted molecular mass of 26.8 kDa (14.4 kDa alpha monomer, 12.4 kDa beta monomer).
