HLA-A*0201 & B2M & EBV EBNA3C (LLDFVRFMGV)

Source

Biotinylated Human HLA-A*02:01&B2M&EBV EBNA3C (LLDFVRFMGV) Complex Protein (HLC-H82E8) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-A*02:01) & Ile 21 - Met 119 (B2M) & LLDFVRFMGV peptide (Accession # AAA59606.1 (HLA-A*02:01) & P61769-1 (B2M) & LLDFVRFMGV).

Predicted N-terminus: Gly 25 & Leu

Molecular Characterization

Biotinylated Human HLA-A*02:01&B2M&EBV EBNA3C (LLDFVRFMGV) Complex Protein is produced by co-expression of HLA and B2M loaded with EBV EBNA3C 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 13.9 kDa. The protein migrates as 41-43 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.

Purity

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

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

Background

The peptide LLDFVRFMGV, derived from the Epstein-Barr virus nuclear antigen EB3C, is presented by the HLA-A*02:01/β2m complex. This peptide-MHC complex serves as a major target for cytotoxic T lymphocytes (CTLs) in the immune control of EBV infection. Its robust immunogenicity makes it a key antigen of interest for studying EBV-specific T-cell responses and for developing immunotherapies against EBV-associated diseases.
