Cat#:RP-2276R;Product Name:Recombinant Rat Activin-A Protein;Synonym:Inhba, Inhibin beta A, FSH releasing protein.;Description:Active form Activin-A Rat Recombinant produced in E.coli is a homodimeric, non-glycosylated, polypeptide chain containing 2 x 117 amino acids and having a molecular weight of 26.2kDa. The Active form Activin-A is purified by standard chromatographic techniques.;Source:E.Coli.;AA Sequence:MGLECDGKVN ICCKKQFFVS FKDIGWNDWI IAPSGYHANY CEGECPSHIA GTSGSSLSFH STVINHYRMR GHSPFANLKS CCVPTKLRPM SMLYYDDGQN IIKKDIQNMI VEECGCS.;Purity:>95% as obsereved by SDS-PAGE.;Bioactivity:Biological activity is assessed by the ability to induce cytoxicity of MPC-11 cells and was found to be 1-1.5 ng/ml corresponding to a specific activity of 666,667-1,000,000 Units/mg.;Formulation:Rat Activin-A was lyophilized from a concentrated 1mg/ml protein solution containing 0.02% TFA.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:Rat INHBA protein should be reconstituted in distilled pyrogen free water to a concentration of 100ug /ml which can then be further diluted to other aqueous solutions.;Storage:Lyophilized Activin-A although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Activin-A 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.;
