Cat#:RP-3216H;Product Name:Recombinant Human FGF21 Protein;Synonym:Fibroblast growth factor 21, FGF-21.;Description:Fibroblast Growth Factor -21 Protein produced in E.coli is a single, non-glycosylated, polypeptide chain containing 182 amino acids and an N-terminal Methionin (bold), having a molecular weight of 19.5 kDa. The FGF-21 is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:MHPIPDS SPLLQFGGQV RQRYLYTDDA QQTEAHLEIR EDGTVGGAAD QSPESLLQLK ALKPGVIQIL GVKTSRFLCQ RPDGALYGSL HFDPEACSFR ELLLEDGYNV YQSEAHGLPL HLPGNKSPHR DPAPRGPARF LPLPGLPPAP PEPPGILAPQ PPDVGSSDPL SMVGPSQGRS PSYAS.;Purity:Greater than 95.0% as determined by SDS-PAGE.;Bioactivity:The ED50 as determined by the dose dependent stimulation of the proliferation of BAF3 cells expressing FGF receptors is 0.06-0.4µg/ml in the presence of betaKlotho and Heparin.;Formulation:Lyophilized from PBS, pH 7.4.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Fibroblast Growth Factor-21 Human Recombinant sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized FGF-21 Human Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Fibroblast Growth Factor 21 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.;
