Recombinant Protein;1MG;Human NRG1 Beta 1, Fc Tag (NR1-H5268) is expressed from human 293 cells (HEK293). It contains AA Ser 2 - Lys 246 (Accession # Q02297-6).;This protein carries a human IgG1 Fc tag at the N-terminus. The protein has a calculated MW of 53.2 kDa. The protein migrates as 65-80 kDa and 90 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.;Immobilized Human ErbB3, His Tag (Cat. No. ER3-H5223) at 2 μg/mL (100 μL/well) can bind Human NRG1 Beta 1, Fc Tag (Cat. No. NR1-H5268) with a linear range of 0.5-8 ng/mL (QC tested).;Immobilized Human ErbB4, His Tag (Cat. No. ER4-H5221) at 2 μg/mL (100 μL/well) can bind Human NRG1 Beta 1, Fc Tag (Cat. No. NR1-H5268) with a linear range of 0.5-8 ng/mL (Routinely tested).
