PDGF1, PDGF-A, PDGFAA, PDGF-AA
Description
PDGF has three subforms: PDGF-AA, PDGF-BB, PDGF-AB. It is involved in a number of biological processes, including hyperplasia, embryonic neuron development, chemotaxis, and respiratory tubule epithelial cell development. The A-chain homodimers of the platelet-derived growth factor (PDGF AA) are widely expressed in normal and transformed cells. The mitogenic properties of PDGF AA are well established. FGF-2 and platelet-derived growth factor-A (PDGF-AA) are potent modulators of oligodendrocytes, the main responsible cells for myelin regeneration. PDGF has been suggested to have a significant role in wound healing.

Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Purity
>98% by SDS-PAGE analyses.
Biological Activity
The ED50 as determined by a cell proliferation assay using murine Balb/c 3T3 cells is less than 5.0 ng/mL, corresponding to a specific activity of > 2.0 × 105 IU/mg. Fully biologically active when compared to standard.
Endotoxin
< 0.1 EU per 1μg of the protein by the LAL method.
Formulation
Lyophilized from a 0.2 μm filtered concentrated solution in 30% Acetonitrile and 0.1% TFA.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in 4mM HCl to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions.
