Recombinant Protein;1MG;Human Insulin R (28-944), His Tag (SPR verified) (INR-H52Ha) is expressed from human 293 cells (HEK293). It contains AA His 28 - Lys 944 (Accession # P06213-2).;This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 106.5 kDa. The protein migrates as 115-125 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.;Immobilized Human Insulin R (28-944), His Tag (Cat. No. INR-H52Ha) at 5 μg/mL (100 μL/well)can bind Human IGF-II, Fc Tag (Cat. No. IG2-H4260) with a linear range of 0.078-1.25 μg/mL (QC tested).;Immobilized Human Insulin R (28-944), His Tag (Cat. No. INR-H52Ha) at 5 μg/mL (100 μL/well)can bind Insulin Biotin Conjugate with a linear range of 0.02-0.313 μg/mL (Routinely tested).;Human Insulin R (28-944), His Tag (Cat. No. INR-H52Ha) captured on CM5 chip via anti-His antibody, can bind Human Insulin with an affinity constant of 249 nM as determined in a SPR assay (Biacore T200) (QC tested).
