Recombinant Protein;200UG;Biotinylated Human IL-2, Fc,Avitag (IL2-H82F3) is expressed from human 293 cells (HEK293). It contains AA Ala 21 - Thr 153 (Accession # P60568-1).;This protein carries a human IgG1 Fc tag at the N-terminus and an Avi tag at the C-terminus. The protein has a calculated MW of 43.7 kDa. The protein migrates as 45-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.;Immobilized Biotinylated Human IL-2, Fc,Avitag (Cat. No. IL2-H82F3) at 1 μg/mL (100 μL/well) on streptavidin precoated (0.2 μg/well) plate, can bind Human IL-2 R alpha, His Tag (Cat. No. ILA-H52H9) with a linear range of 1-39 ng/mL (QC tested).;Immobilized Human IL-2 R alpha, Fc Tag (Cat. No. ILA-H5251) at 5 μg/mL (100 μL/well) can bind Biotinylated Human IL-2, Fc,Avitag (Cat. No. IL2-H82F3) with a linear range of 0.6-10 ng/mL (Routinely tested).
