Biotinylated Human HLA-A*33:03&B2M Monomer Protein (Peptide free, MALS verified)

Biotinylated Human HLA-A*33:03&B2M Monomer Protein (Peptide free, MALS verified)

• Description: Biotinylated Human HLA-A*33:03&B2M Monomer Protein (HLM-H82W2) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Thr 305 (HLA-A*03:03) & Ile 21 - Met 119 (B2M) (Accession # AAA79865.1 (HLA-A*03:03) & P61769-1 (B2M)).
• Specifications: This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™). The protein has a calculated MW of 39.4 kDa and 15.7 kDa. The protein migrates as 43-48 kDa and 16 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
