Source

Biotinylated Human HLA-A*31:01&B2M&EGF R (HVKITDFGR) Complex Protein (HLR-H82Ee) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Thr 305 (HLA-A*31:01) & Ile 21 - Met 119 (B2M) & HVKITDFGR peptide (Accession # QBM15381.1 (HLA-A*31:01) & P61769 (B2M) & HVKITDFGR).

Predicted N-terminus: Gly 25 & His

Molecular Characterization

Biotinylated Human HLA-A*31:01&B2M&EGF R (HVKITDFGR) Complex Protein is produced by co-expression of HLA-A*31:01 and B2M loaded with EGF R peptide.

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

The protein has a calculated MW of 36 kDa and 13.8 kDa. The protein migrates as 39-43 kDa and 12 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.
