| Purity | Greater than 98.0% as determined by SDS-PAGE. | Source | Saccharomyces cerevisiae. |
| Phycical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | Shipping Condition | Shipped at Room temp. |
| Synonyms | Glioma-derived growth factor; GDGF; Osteosarcoma-derived Growth Factor; ODGF; SIS; SSV; PDGF2; c-sis; FLJ12858; PDGF-BB; PDGF B-chain; Platelet-derived growth factor beta polypeptide; Becaplermin. | ||
| Amino Acid Sequence | The sequence of the first five N-terminal amino acids was determined and was found to be Ser-Leu-Gly-Ser-Leu. | ||
| Solubility | It is recommended to reconstitute the lyophilized Platelet-derived Growth Factor-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 .Please prevent freeze-thaw cycles. | ||
| Biological Activity | The ED50, as measured by its ability to stimulate proliferation of mouse 3T3 fibroblasts is typically 1 ng/ml, corresponding to a Specific Activity of 1,000,000IU/mg. | ||
| Formulation | The PDGF-BB was lyophilized from 0.2 µm filtered solution in 20mM sodium phosphate in absence of any carrier protein. | ||
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.
