表达区间及表达系统（Source）

Rat FCGRT&B2M Heterodimer Protein, His Tag&Strep II Tag (FCM-R5287) is expressed from human 293 cells (HEK293). It contains AA Ala 23 - Ser 298 (FCGRT) & Ile 21 - Met 119 (B2M) (Accession # P13599-1 (FCGRT) & P07151-1 (B2M)).

Predicted N-terminus: Ala 23 (FCGRT) & Ile 21 (B2M)

蛋白结构（Molecular Characterization）

Rat FCGRT&B2M Heterodimer Protein, His Tag&Strep II Tag, produced by co-expression of FCGRT and B2M, has a calculated MW of 31.8 kDa (FCGRT) and 13.1 kDa (B2M). Subunit FCGRT is fused with a polyhistidine tag at the C-terminus and subunit Beta-2 microglobulin (B2M) is fused with Strep II-tag at the C-terminus. The reducing (R) protein migrates as 43-55 kDa (FCGRT) and 14 kDa (B2M) respectively due to different glycosylation.
