Product Source: Protein is expressed in E.coli.
The protein is manufactured without the use of any animal products/reagents and is considered Animal-Free and can be used in protocols where possible transmisson of animal viruses and contamination must be avoided.
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 -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- and PDGFR-. PDGFR- is high-affinity receptor for each of the three PDGF forms. On the other hand, PDGFR- interacts with only PDGFBB and PDGF-AB.
Recombinant human PDGF-AA is a 28.5 kDa disulfide-linked homodimer of two A chains (250 total amino acids).

Quality
Determined by the dose-dependent stimulation of the proliferation of Balb/c 3T3 cells. The expected ED50 for this effect is 1.0-3.0 ng/ml.
Physical form
Product is presented in 10mM Acetic Acid and is filtered through a 0.2 micron filter before lyophilization.
Storage and Stability
Store at -20°C for up to 4 months from date of receipt Centrifuge the vial prior to opening.
Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein and store in working aliquots at -20°C.
