Source
Biotinylated Cynomolgus / Rhesus macaque FcRn Heterodimer Protein, His,Avitag (FCM-C82W3) is expressed from human 293 cells (HEK293). It contains AA Ala 24 - Ser 297 (FCGRT) & Ile 21 - Met 119 (B2M) (Accession # Q8SPV9-1 (FCGRT) & Q8SPW0-1 (B2M)). In the region Ala 24 - Ser 297 (FCGRT) & Ile 21 - Met 119 (B2M), the amino acid sequences of Cynomolgus and Rhesus macaque FcRn (FCGRT & B2M) are identical.
Predicted N-terminus: Ala 24 (FCGRT) & Ile 21 (B2M)

Other Tags and Version Biotin & Other Labeled Version
Biotinylated Cynomolgus / Rhesus macaque FcRn Heterodimer Protein, His,Avitag, produced by co-expression of FCGRT and B2M, has a calculated MW of 34.1 kDa (FCGRT) and 11.6 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 at the C-terminus. The reducing (R) protein migrates as 35-40 kDa (FCGRT) and 13 kDa (B2M) respectively due to glycosylation.
