Recombinant Protein;1MG;Human IL-2RB&IL-2RG Heterodimer Protein, His Tag&Twin-Strep Tag (ILG-H5283) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Asp 239 (IL-2RB) & Leu 23 - Asn 254 (IL-2RG) (Accession # P14784-1 (IL-2RB) & P31785-1 (IL-2RG)).;Human IL-2RB&IL-2RG Heterodimer Protein, His Tag&Twin-Strep Tag is produced by co-expression of IL-2RB and IL-2RG, has a calculated MW of 29.9 kDa (IL-2RB) and 34.1 kDa (IL-2RG). Subunit IL-2RB is fused with a polyhistidine tag at the C-terminus and subunit IL-2RG is fused with Twin-Strep tag at the C-terminus. The reducing (R) protein migrates as 40-44 kDa and 60-65 kDa respectively due to glycosylation.;Immobilized Human IL-2, Tag Free (Cat. No. IL2-H4113) at 5 μg/mL (100 μL/well) can bind Human IL-2RB&IL-2RG Heterodimer Protein, His Tag&Twin-Strep Tag (Cat. No. ILG-H5283) with a linear range of 20-78 ng/mL (QC tested).
