Human Activin RIB & Activin RIIB Protein, Fc Tag

Human Activin RIB & Activin RIIB Protein, Fc Tag&Fc Tag is produced by co-expression of Activin RIB and Activin RIIB, has a calculated MW of 37 kDa & 39.1 kDa. Subunit Activin RIB is fused with a human IgG1 Fc tag at the C-terminus and subunit Activin RIIB is fused with a human IgG1 Fc tag at the C-terminus. The protein migrates as 80-95 kDa and >150 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
