Technical Data
Platelet Derived Growth Factor AA, Recombinant, Human (PDGF-AA)
Molecular Biology Storage: -20CShipping: RT
PDGFs are disulfide-linked dimers consisting of two 12.0-13.5kD 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 28.5kD disulfide-linked homodimer of two A chains (250aa).F.

Biological Activity:
Determined by the dose-dependent stimulation of thymidine uptake by Balb/c 3T3 cells. The expected ED50 for this effect is 1ng/ml.

Concentration Range: 0.2-10ng/ml for most in vitro applications.

AA Sequence:

Storage and Stability:
Lyophilized powder may be stored at -20C Stable for 12 months. Reconstitute with 10mM acetic acid. Aliquot and store at -20C. Reconstituted product is stable for 3 months with a carrier protein. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
