Synonyms

MR1 & B2M

Source

Biotinylated Human MR1&B2M Complex Protein (MRM-H82W5) is expressed from human 293 cells (HEK293). It contains AA Arg 23 - Met 302 (Accession # Q95460-1 (MR1) & P61769-1 (B2M)).

Predicted N-terminus: Arg 23 & Ile 21

Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 36.3 kDa and 11.7 kDa. The protein migrates as 42-45 kDa and 13 kDa under reducing (R) condition (SDS-PAGE) 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.

Purity

>95% as determined by SDS-PAGE.
