Other Tags and Version Biotin & Other Labeled Version
Human FCGRT&B2M Heterodimer Protein, Strep Tag&Tag Free, produced by co-expression of FCGRT and B2M, has a calculated MW of 33.8 kDa (FCGRT) and 11.7 kDa (B2M). Subunit FCGRT is fused with Strep II-tag at the C-terminus and subunit Beta-2 microglobulin (B2M) contains no tag. The reducing (R) protein migrates as 40-43 kDa (FCGRT) and 12 kDa (B2M) when calibrated against Star Ribbon Pre-stained Protein Marker respectively due to glycosylation.
