Description of Human PDGF-AB
PDGFs are disulfide-linked dimers consisting of two 12.0-13.5 kDa polypeptide chains, designated PDGF-A and PDGF-B chains. The three naturally occurring PDGFs; PDGF-AA, PDGF-BB and PDGF-AB, are potent mitogens for a variety of cell types including smooth muscle cells, connective tissue cells, bone and cartilage cells, and some blood cells. The PDGFs are stored in platelet a-granules and are released upon platelet activation. The PDGFs are involved in a number of biological processes, including hyperplasia, chemotaxis, embryonic neuron development, and respiratory tubule epithelial cell development. Two distinct signaling receptors used by PDGFs have been identified and named PDGFR-a and PDGFR-ß. PDGFR-a is high-affinity receptor for each of the three PDGF forms. On the other hand, PDGFR-ß interacts with only PDGF-BB and PDGF-AB. Recombinant human PDGF-AB is a 25.5 kDa disulfide-linked dimer, consisting of one A chain and one B chains (234 total amino acids).
The biological activity was determined by the induction of proliferation in NHDF cells (Normal Human Dermal Fibroblasts).
Centrifuge vial prior to opening. The lyophilized PDGF-AB should be reconstituted in 50mM acetic acid to a concentration not lower than 100µg/ml. For long term storage of reconstituted protein addition of carrier protein (e.g. BSA or HSA; 0.1%) is recommended.
