HLA-A*0201 & B2M & HCV NS3 (CINGVCWTV)

Source

Biotinylated Human HLA-A*02:01&B2M&HCV NS3 (CINGVCWTV) Complex Protein (HL3-H82E3) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-A*02:01) & Ile 21 - Met 119 (B2M) & CINGVCWTV peptide (Accession # AAA59606.1 (HLA-A*02:01) & P61769-1 (B2M) & CINGVCWTV).

Predicted N-terminus: Gly 25 & Ile 21

Molecular Characterization

Biotinylated Human HLA-A*02:01&B2M&HCV NS3 (CINGVCWTV) Complex Protein is produced by co-expression of HLA-A and B2M loaded with HCV NS3 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 40-43 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.

>90% as determined by SEC-HPLC.

Formulation

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

Background Introduction

Hepatitis C virus (HCV) is a single-stranded R virus that causes hepatitis C. It is prone to causing chronic hepatitis and can progress to liver cirrhosis and liver cancer. NS3 has serine protease activity (at the N-terminus, assisting in the cleavage of viral polyproteins) and helicase/nucleoside triphosphatase activity (at the C-terminus, participating in R unwinding and replication), and it is the main target of anti-HCV virus drugs (such as protease inhibitors). The Human HLA-A*0201 HCV NS3 (CINGVCWTV) complex protein is a complex of HLA-A*0201 of the MHC Class I, B2M and CINGVCWTV peptide of the HCV NS3.
