Cat#:CTLA4-118HAC;Product Name:Recombinant Human CTLA-4 / CD152 Protein(Fc Tag);Synonym:CTLA4,CD152,CELIAC3,GRD4,GSE,ICOS,IDDM12;Description:Human CTLA-4 with Fc Tag is produced in HEK293 cells. It contains AA Ala 37 - Ser 160.;Source:HEK293;Predicted N Terminal:Ala 37;Molecular Characterization:Recombinant human CTLA-4 / CD152 protein has a calculated molecular weight of 40 kDa. As a result of glycosylation, The recombinant protein migrates as 50-55 kDa under reducing (R) condition, and 100-110 kDa under non-reducing (NR) condition (SDS-PAGE).;Purity:Greater than 98% as determined by SDS-PAGE.;Endotoxin:<1.0 EU per μg of recombinant human CTLA-4 / CD152 protein by the LAL method.;Formulation:Recombinant human CTLA-4 / CD152 protein was lyophilized from 0.22 μm filtered solution in 35 mM Tris, 50 mM NaCl, 50 mM Glycine, pH8.0.;Stability:Recombinant human CTLA-4 / CD152 protein was stable up to 1 year from date of receipt at -70℃;Storage:Store recombinant human CTLA-4 / CD152 protein under sterile conditions at -20℃ to -80℃. It is recommended that the recombinant protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.;Usage:For Lab Research Use Only;
