HLA-A*0201 & B2M & HBV (FLLTKILTI)

Source

PE-Labeled Human HLA-A*02:01&B2M&HBV (FLLTKILTI) Tetramer Protein (HLV-HP2E3) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-A*02:01) & Ile 21 - Met 119 (B2M) & FLLTRILTI peptide (Accession # AAA59606.1 (HLA-A*02:01) & P61769-1 (B2M) & FLLTRILTI).

Predicted N-terminus: Gly 25 & Ile 21

Molecular Characterization

PE-Labeled Human HLA-A*02:01&B2M&HBV (FLLTKILTI) Tetramer Protein is assembled by biotinylated monomer and PE-labeled streptavidin.

Biotinylated Human HLA-A*02:01&B2M&HBV (FLLTKILTI) Complex Protein is produced by co-expression of HLA-A*02:01 and B2M loaded with HBV peptide. Biotinylated Human HLA-A*02:01&B2M&HBV (FLLTKILTI) Complex Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

Background Introduction

The surface antigens (HBsAg) decorating the lipid envelope of HBV are produced in excess during the life cycle of the virus, and its presence in blood indicates current hepatitis B infection. The Human HLA-A*0201 HBV ( FLLTKILTI) complex protein is a complex of HLA-A*0201 of the MHC Class I, B2M, and FLLTKILTI peptide of the HBV.
