Source

Human FCGRT&B2M Heterodimer Protein, Strep Tag&Tag Free (FCM-H5283) is expressed from human 293 cells (HEK293). It contains AA Ala 24 - Ser 297 (FCGRT) & Ile 21 - Met 119 (B2M) (Accession # P55899-1 (FCGRT) & P61769-1 (B2M)).

Predicted N-terminus: Ala 24 (FCGRT) & Ile 21 (B2M)

Molecular Characterization

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.
