Recombinant Human PDGF-BB produced in E.Coli is a double, non-glycosylated, polypeptide chain containing 109 amino acids and having a molecular mass of 24,525 Dalton. The ED50, calculated by the dose-dependant proliferation of murine BALB/c 3T3 indicator cells (measured by 3H-thymidine uptake) is <0.1ng/mL, corresponding to a Specific Activity of 1 MIU/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.
Purity: > 98.0% (by RP-HPLC, IEX-HPLC, SDS-PAGE). Less than 1% dimers and aggregates. Sterile Filtered White lyophilized (freeze-dried) powder. The lyophilized rHuPDGF-BB is soluble in water and most aqueous buffers above the isoelectric point.
