Other Tags and Version Biotin & Other Labeled Version
Biotinylated Mouse FCGRT&B2M Heterodimer Protein, His,Avitag, produced by co-expression of FCGRT and B2M, has a calculated MW of 34.9 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 45-55 kDa (FCGRT) and 13 kDa (B2M) respectively due to glycosylation.
Labeling
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

I used Acro's FcRn for development of novel assays. The proteins within just a few days of placing the order. The proteins were also high quality, stable, and did not result in any background in any of the assays that were developed, even after using them for months. These produced great data and we have continued to repurchase them since. I would highly recommend this product.
