Description: 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 alpha-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-alpha and PDGFR-beta. PDGFR-alpha is high-affinity receptor for each of the three PDGF forms. On the other hand, PDGFR-beta interacts with only PDGF-BB and PDGF-AB. Recombinant human PDGF-AA is a 28.5 kDa disulfide-linked homodimer of two A chains (250 total amino acids).

Purity Confirmation: > 95% by SDS-PAGE

Endotoxin: < 0.1 ng per ug of PDGF-AA

Formulation: lyophilized

Storage Handling Stability: The lyophilized PDGF-AA is stable for a few weeks at room temperature, but best stored at -20°C. Reconstituted PDGF-AA is best stored at -20°C to -70°C. Avoid repeated freeze-thaw cycles.

Reconstituation: Centrifuge vial prior to opening. The lyophilized PDGF-AA should be reconstituted in water to a concentration not lower than 50 µg/ml. For long term storage we recommend to add at least 0.1% human or bovine serum albumin.

Molecular Weight: 28.5 kDa

Lenght (aa): 125
