The activity was measured by its ability to stimulate the proliferation of 3T3 cells.
Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile 10mM acetic acid containing 0.1% endotoxin-free recombinant human serum albumin.
Stability & Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles. In general: 12 months from date of receipt, -20 to -80°C as supplied. 1 month, 2 to 8°C under sterile conditions after reconstitution. 3 months, -20 to -80°C under sterile conditions after reconstitution.
PDGF is not one molecule but three, each a dimeric combination of two distinct but structurally related peptide chains designated A and B. The dimeric isoforms PDGFaa, ab and bb are differentially expressed in various cell types and their effects are mediated through two distinct receptors, termed α and β. The PDGFs play an essential role in the regulation of embryonic development, cell proliferation, cell migration, survival and chemotaxis. They are involved in a number of biological processes, including hyperplasia, chemotaxis, embryonic neuron development, and respiratory tubule epithelial cell development.
