PDGF-BB Equine

Source:Escherichia Coli.Physical Appearance:Sterile Filtered White lyophilized (freeze-dried) powder.Biological ActivityThe ED50 as determined by 3T3 proliferation is = 30 ng/mL, corresponding to a specific activity of = 3.3 x 10^4 units/mg.PDGF-BB is a member of the platelet-derived growth factor family. The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a motif of eight cysteines. This gene product can exist either as a homodimer (PDGF-BB) or as a heterodimer with the platelet-derived growth factor alpha polypeptide (PDGF-AB), where the dimers are connected by disulfide bonds. Mutations in this gene are associated with meningioma. Reciprocal translocations between chromosomes 22 and 7, at sites where this gene and that for COL1A1 are located, are associated with a particular type of skin tumor called dermatofibrosarcoma protuberans resulting from unregulated expression of growth factor. Two splice variants have been identified for this gene.PDGF-BB Equine Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide dimer chain containing 2 x 110 amino acids and having a total molecular mass of 24.8kDa.The PDGF-BB is purified by proprietary chromatographic techniques.
