Background: PDGF-BB

Platelet-derived growth factor is a dimeric glycoprotein composed of two A (-AA) or two B (-BB) chains or a combination of the two (-AB). All PDGFs function as secreted, disulphide-linked homodimers, but only PDGFA and B can form functional heterodimers. PDGFs are mitogenic during early developmental stages, driving the proliferation of undifferentiated mesenchyme and some progenitor populations. PDGF is a required element in cellular division for fibroblasts, a type of connective tissue cell that is especially prevalent in wound healing. In essence, the PDGFs allow a cell to skip the G1 checkpoints in order to divide. Recombinant rat PDGF-AA contains 109 amino acids and has a molecular mass of 12.2 kDa.

FAQs for Recombinant Rat PDGF-BB Protein

Showing  1 - 1 of 1 FAQ Showing All
  • Q: I purchased the Rat PDGF-BB protein, but I cannot find the specificity. Does it cross-react only with RAT or also with other species?

    A: Regarding the specificity of the active protein, the homology of this amino acid sequence is quite high among rats and other rodents~98-100% and with primates there is about ~89% homology. Therefore, one might assume that you could use this active protein in assays for some animals other than rats. I am not sure what the parameters are for your assay are but if you tell me more about it, I might be able to provide more specific information.  If you need an antibody to this protein, here are 3 antibodies to the human protein that have not been validated in any other species.
