Cat#:RP-1761M;Product Name:Recombinant Mouse FST Protein;Synonym:Follistatin, FST, FS, Activin-binding protein, AL033346.;Description:Follistatin Mouse Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 289 amino acids and having a total molecular mass of 31.6kDa. The FST is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:MGNCWLRQAK NGRCQVLTKT ELSKEECCST GRLSTSWTEE DVNDNTLFKW MIFNGGAPNC IPCKETCENV DCGPGKKCRM NKKNKPRCVC APDCSNITWK GPVCGLDGKT YRNECALLKA RCKEQPELEV QYQGRCKKTC RDVFCPGSST CVVDQTNNAY CVTCNRICPE PASSEQYLCG NDGVTYSSAC HLRKATCLLG RSIGLAYEGK CIKAKSCEDI QCTGGKKCLW DS;Purity:Greater than 90.0% as determined by SDS-PAGE.;Bioactivity:The ED50, determined by the dose-dependent neutralization of 7.5ng/ml human Activin-A on MCP-11 cells, is 0.13-0.19µg/ml.;Formulation:The Mouse Follistatin is lyophilized from 10mM Na2PO4 and 50mM NaCl, pH 7.5.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Follistatin in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized Follistatin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FST 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.;
