分子别名（Synonym）

FcRn,FCGRT & B2M

表达区间及表达系统（Source）

Biotinylated Feline FCGRT&B2M Heterodimer Protein, His,Avitag (FCN-F82W3) is expressed from human 293 cells (HEK293). It contains AA Ala 24 - Ser 297 (FCGRT) & Val 21 - Met 118 (B2M) (Accession # W5VRL5-1 (FCGRT) & Q5MGS7-1 (B2M)).

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

蛋白结构（Molecular Characterization）

Biotinylated Feline FCGRT&B2M Heterodimer Protein, His,Avitag, produced by co-expression of FCGRT and B2M, has a calculated MW of 34.0 kDa (FCGRT) and 11.5 kDa (B2M). Subunit FCGRT is fused with a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™) and subunit Beta-2 microglobulin (B2M) contains no tag. The reducing (R) protein migrates as 36-40 kDa (FCGRT) and 18-20 kDa (B2M) respectively due to glycosylation.
