Cat#:RP-5983H;Product Name:Recombinant Human TACI Protein;Synonym:CD267, CVID, CVID2, TACI, TNFRSF14B, Tumor necrosis factor receptor superfamily, member 13B, Tumor necrosis factor receptor superfamily, member 13B, isoform CRA_a, TNFRSF13B. ;Description:TACI Protein produced in E.coli is a single, non-glycosylated, polypeptide chain containing 160 amino acids and having a molecular mass of 18.0kDa.?;Source:E.coli;AA Sequence:MSGLGRSRRG GRSRVDQEER FPQGLWTGVA MRSCPEEQYW DPLLGTCMSC KTICNHQSQR TCAAFCRSLS CRKEQGKFYD HLLRDCISCA SICGQHPKQC AYFCENKLRS PVNLPPELRR QRSGEVENNS DNSGRYQGLE HRGSEASPAL PGLKLSADQV ;Purity:Greater than 95.0% as determined by:  (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:Fully biologically active when compared to standard. The biological activity is determined by its ability to block human BAFF induced T2B cell survival using a concentration range of 1.0-3.0 µg/ml corresponding to a specific activity of 334-1000 IU/mg.;Formulation:TACI protein was lyophilized from a 0.2 µm filtered concentrated solution in 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 TACI in sterile 18M?-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized TACI although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TACI 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.;
