||Fibroblast growth factor receptor-1 beta (FGFR1- beta) is an isoform of FGFR1 which is a receptor tyrosine kinase. FGF R1β supports progression and chemoresistance in subsets of acute myeloid leukemias (AML).
||The predicted molecular weight of Recombinant Human FGF R1β (IIIb) is Mr 56 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 90-100 kDa.
|State Of Matter:
||> 95% by SDS Page and analyzed by silver stain.
||< 1.0 EU/µg as determined by the LAL method.
|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.
