Synonyms

H-2Kb & B2M & OVA (SIINFEKL)

Source

Biotinylated Mouse H-2Kb&B2M&OVA (SIINFEKL) Complex Protein (H2A-M82T3) is expressed from human 293 cells (HEK293). It contains AA Gly 22 - Met 305 (H-2Kb) & Ile 21 - Met 119 (B2M) & SIINFEKL peptide (Accession # P01901 (H-2Kb) & P01887 (B2M) & SIINFEKL).

Predicted N-terminus: Gly 22 & Ser

Molecular Characterization

Biotinylated Mouse H-2Kb&B2M&OVA (SIINFEKL) Complex Protein is produced by co-expression of H-2Kb and B2M loaded with OVA peptide.

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

The protein has a calculated MW of 39.3 kDa and 17.6 kDa. The protein migrates as 47-50 kDa and 21 kDa when calibrated against Star Ribbon Pre-stained Protein Marker 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

>90% as determined by SDS-PAGE.
