Synonym

HLA-A*02:01 & B2M & NY-ESO-1 (SLLMWITQV)

Source

Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) Tetramer Protein (HL1-H52E7) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-A*02:01) & Ile 21 - Met 119 (B2M) & SLLMWITQV peptide (Accession # AAA59606.1 (HLA-A*02:01) & P61769 (B2M) & SLLMWITQV).

Predicted N-terminus: Gly 25 & Ser

Molecular Characterization

Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) Tetramer Protein is assembled by biotinylated monomer (HL1-H82E4) and streptavidin.

Biotinylated Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) Complex Protein is produced by co-expression of HLA and B2M loaded with NY-ESO-1 peptide. Biotinylated Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) Complex 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, 13.8 kDa and 13.3 kDa. The protein migrates as 42-45 kDa, 15 kDa and 14 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin
