Cat#:RP-3241H;Product Name:Recombinant Human FGFR4 Protein;Synonym:Fibroblast Growth Factor Receptor 4, EC 2.7.10.1, JTK2, TKF, Tyrosine Kinase Related To Fibroblast Growth Factor Receptor, Hydroxyaryl-Protein Kinase, Protein-Tyrosine Kinase, Tyrosylprotein Kinase, CD334 Antigen, EC 2.7.10, FGFR-4, CD334, FGFR4.;Description:Soluble FGFR-4a (IIIc) Fc Chimera Protein fused with Xa cleavage site with the Fc part of human IgG1 produced in baculovirus is a heterodimeric, glycosylated, Polypeptide chain and having a molecular mass of 170 kDa. The FGFR4 is purified by proprietary chromatographic techniques.;Source:Insect Cells.;Purity:Greater than 90.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:Determined by its ability to inhibit human FGF acidic-dependent proliferation on R1 cells. The ED50 for this effect is typically at 15.0-30.0 ng/ml.;Formulation:CD334 was lyophilized from a concentrated (1mg/ml) sterile solution containing no additives.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized FGFR-4 in sterile PBS not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized FGFR4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FGFR4 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
