Recombinant Human Fibroblast Growth Factor Receptor 1(IIIb)

Specification :
| Cat. No. : FGFR1-485H | Description : Fibroblast growth factor receptor-1 alpha (FGFR1-alpha) is an isoform of FGFR1 which is a receptor tyrosine kinase. FGFR1-alpha is expressed in prostate luminal epithelial cells. FGFR1alpha signals are posteriorizing factors that control node regression and posterior embryonic development. FGFR1-alpha is a splice variant of FGFR1 containing the first immunoglobulin-like domain, whereas FGFR1-beta lacks this domain. The presence or absence of this N-terminal domain influences the affinity of the receptor towards aFGF and heparin. | Source : Mammalian cells | Molecular Weight : The predicted molecular weight of Recombinant Human FGF R1α (IIIb) is Mr 66 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 110-120 kDa. | State Of Matter : Lyophilized. | Purity : > 95% by SDS Page and analyzed by silver stain. | Endotoxin : | Storage And Stability : This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
