PDGF-BB, Rat Recombinant, produced in
Escherichia coli is a disulfide-linked homodimeric, non-glycosylated, polypeptide of two B chains containing 2x109 amino acids (218 amino acids in total) and having a molecular mass of 24.4 kDa. The PDGF-BB is purified by proprietary chromatographic techniques.
Synonyms: Platelet-derived growth factor subunit B, PDGF subunit B, PDGF-2, Platelet-derived growth factor B chain, Platelet-derived growth factor beta polypeptide, Pdgfb, SIS, c-sis.
Formulation: PDGF-BB was lyophilized from a 0.2 µm filtered concentrated solution in 1xPBS, pH 7. 0.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Purity: Greater than 98% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Solubility: It is recommended to reconstitute the lyophilized PDGF-BB in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability: Lyophilized Platelet-derived Growth Factor BB although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution PDGF BB should be stored at +4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Biological Activity: The ED50as determined by a cell proliferation assay using murine Balb/c 3T3 cells is less than 2 ng/ml, corresponding to a specific activity of > 5 × 105 IU/mg.
