Product Description PDGF 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. Product Properties Synonyms PDGF1, PDGF-A, PDGFAA, PDGF-AA Accession P04085 GeneID 5154 Source E.coli-derived human PDGF-AA, Ser87-His211, with an N-terminal Met.

Purity >95% by SDS-PAGE analyses. Biological Activity The ED50 for this effect is 50-200 ng/mL in a fluorometric assay using the redox sensitive dye. Measured in a cell proliferation assay using NR6R-3T3 mouse fibroblast cells. Endotoxin < 0.1 EU per 1μg of the protein by the LAL method. Formulation Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, 300 mM NaCl, pH 6.0. Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA 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. Shipping and Storage The products are shipped with ice pack and can be stored at -20℃ for 1 year. 1 month, 2 to 8 °C under sterile conditions after reconstitution.3 months, -20 °C under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles. Cautions 1.Avoid repeated freeze-thaw cycles. 2.For your safety and health, please wear lab coats and disposable gloves for operation. 3.For research use only.
