HLA-A*0201 & B2M & EBV EBNA (FMVFLQTHI)

Source

Biotinylated Human HLA-A*02:01&B2M&EBV EBNA (FMVFLQTHI) Complex Protein (HLA-H82E8) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-A*02:01) & Ile 21 - Met 119 (B2M) & FMVFLQTHI peptide (Accession # AAA59606.1 (HLA-A*02:01) & P61769-1 (B2M) & FMVFLQTHI).

Predicted N-terminus: Gly 25 & Ile 21

Molecular Characterization

Biotinylated Human HLA-A*02:01&B2M&EBV EBNA (FMVFLQTHI) Complex Protein is produced by co-expression of HLA and B2M loaded with EBV EBNA peptide.

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

The protein has a calculated MW of 36.3 kDa and 11.7 kDa. The protein migrates as 41-43 kDa and 10 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.

>95% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background Introduction

HLA-A*0201, a prevalent MHC class I allele, assembles with β2-microglobulin (B2M) and the EBV EB peptide FMVFLQTHI to form a peptide-MHC complex. As a protein family expressed in EBV latent infection, EB preserves viral genome stability, modulates host cell cycle and enables immune evasion. It is tightly linked to EBV-associated disorders such as infectious mononucleosis and nasopharyngeal carcinoma, acting as a vital target for diagnosis and mechanistic studies. The surface-displayed complex can be recognized by CD8⁺ cytotoxic T cells, supporting research on EBV-specific immunity and immunotherapy development.
