HLA-A*0201 & B2M & CMV pp65 (NLVPMVATV)

Source

Biotinylated Human HLA-A*02:01&B2M&CMV pp65 (NLVPMVATV) Complex Protein (HLC-H82E5) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-A*02:01) & Ile 21 - Met 119 (B2M) & NLVPMVATV peptide (Accession # AAA59606.1 (HLA-A*02:01) & P61769 (B2M) & NLVPMVATV).

Predicted N-terminus: Gly 25 & Ile 21

Molecular Characterization

Biotinylated Human HLA-A*02:01&B2M&CMV pp65 (NLVPMVATV) Complex Protein is produced by co-expression of HLA and B2M loaded with CMV pp65 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 43-48 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

Cytomegalovirus (Cytomegalovirus) is a herpes viral D virus. Human cytomegalovirus (HCMV) can only infect humans and multiply in humans. The antibodies. After primary infection with CMV, the body can produce specific antibodies and killer T lymphocytes to activate NM cells. The antibody has limited CMV replication ability and has a certain resistance to reinfection of the same strain, but cannot resist the activation of antibody-dependent virus and the exogenous infection of other different strains of CMV. However, specific killer T lymphocytes and antibody-dependent cytotoxic cells can exert the greatest antiviral effect. The Human HLA-A*0201 CMV (NLVPMVATV) complex protein is a complex of HLA-A*0201 of the MHC Class I, B2M, and NLVPMVATV peptide of the CMV.
