Human Her2 & ErbB3 Protein, Fc Tag

Human Her2 & ErbB3 Protein, Fc Tag&Fc Tag, produced by co-expression of HER2 and ErbB3, has a calculated MW of 95.9 kDa (HER2) and 94.9 kDa (ErbB3) . Subunit HER2 is fused with a human IgG1 Fc fragment at the C-terminus and subunit ErbB3 is fused with a human IgG1 Fc fragment at the C-terminus. The protein migrates as 110-130 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
