| Source | E. coli |
| Formulation | lyophilized |
| Purity Confirmation | > 95% by SDS-PAGE |
| Length [aa] | 109 |
| Molecular Weight | 24.3 kDa |
| N Terminal Sequence | SLGSL |
| Endotoxin Levels | < 0.1 ng per ug of PDGF-BB |
| Biological Activity | The biological activity was determined by the induction of proliferation in NHDF cells (Normal Human Dermal Fibroblasts). |
| Species Reactivity | Human |
| Buffer | 50mM acetic acid |
| Reconstitution | Centrifuge vial prior to opening. The lyophilized PDGF-BB should be reconstituted in 50mM acetic acid to a concentration not lower than 100μg/ml. For long term storage of reconstituted protein addition of carrier protein (e.g. BSA or HSA; 0.1%) is recommended. |
| Stability and Storage | The lyophilized PDGF-BB is stable for a few weeks at room temperature, but best stored at -20°C. Reconstituted PDGF-BB is best stored at -20°C to -70°C. |
| Synonyms | PDGF-2; Platelet-derived growth factor B chain; Platelet-derived growth factor beta polypeptide; Proto-oncogene c-Sis; INN=Becaplermin |
| Description | PDGFs are disulfide-linked dimers consisting of two 12.0-13.5 kDa polypeptide chains, designated PDGF-A and PDGF-B chains. The three naturally occurring PDGFs; PDGF-AA, PDGF-BB and PDGF-AB, are potent mitogens for a variety of cell types including smooth muscle cells, connective tissue cells, bone and cartilage cells, and some blood cells. The PDGFs are stored in platelet alpha-granules and are released upon platelet activation. The PDGFs are involved in a number of biological processes, including hyperplasia, chemotaxis, embryonic neuron development, and respiratory tubule epithelial cell development. Two distinct signaling receptors used by PDGFs have been identified and named PDGFR-alpha and PDGFR-beta. PDGFR-alpha is high-affinity receptor for each of the three PDGF forms. On the other hand, PDGFR-beta interacts with only PDGF-BB and PDGF-AB. Recombinant human PDGF-BB is a 24.3 kDa disulfide-linked homodimer of two B chains (218 total amino acids). |
