| Cat. No. : |
PDGFB-146H |
| Description : |
The platelet-derived growth factor (PDGF) family consists of four different polypeptide chains; PDGF-A, PDGF-B, PDGF-C and PDGF-D, sharing approximately 25% sequence homology. The biological effects of PDGF-B are exerted via two receptor tyrosine kinases, PDGFRA and PDGFRB. PDGF-B is expressed predominantly in platelets and the heart, but has been detected in the majority of human organs. PDGF-B is a potent mitogen for mesenchymal cells and plays a critical role in wound healing and tumor development. PDGF-B is an important growth factor contributing to angiogenesis and possibly lymphatic metastasis due to lymphangiogenesis. Additionally, PDGF-B plays a crucial role in wound healing. Studies have also suggested that PDGF-B is involved in the CNS including having a neuroprotective or neurotrophic effect in the developing or adult CNS, promoting angiogenic responses to injury in the CNS and remyelination.. |
| Source : |
human 293 cells. |
| Molecular Mass : |
Under reducing conditions PDGF-B migrates as a broad band between 15.2 and 16.1 kDa on SDS-PAGE due to post-translational modifications, in particular glycosylation. This compares with unmodified PDGF-B polypeptide that has a predicted monomeric molecular mass of 12.29 kDa. |
| PI : |
PDGF-B has a predicted pI of 9.38. |
| % Carbohydrate : |
purified PDGF-B consists of 30-45% carbohydrate by weight. |
| Glycosylation : |
PDGF-B contains N-linked oligosaccharides and a predicted O-linked Mannose. |
| Purity : |
>95%, as determined by SDS-PAGE, visualized by Coomassie Brilliant Blue. |
| Formulation : |
When reconstituted in 0.5 ml sterile phosphate-buffered saline, the solution will contain 1% human serum albumin (HSA) and 10% trehalose. |
| Reconstitution : |
It is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial. |
| Storage : |
Lyophilized products should be stored at 2 to 8°C. Following reconstitution short-term storage at 4°C is recommended, with longer-term storage in aliquots at -18 to -20°C. |
| Activity : |
The ED50of PDGF-B is typically 14-25 ng/mL as measured in a cell proliferation assay using the murine Balb/3T3 fibroblast cell line. |
