Hepatitis B Virus Receptor Binding Fragment

Hepatitis B Virus Receptor Binding Fragment is a synthetic hepatitis B virus-derived antigenic peptide. HBV-derived synthetic peptides from core, surface, envelope, polymerase, and other viral proteins are used to characterize virus-specific cellular immunity. Published studies have mapped multiple HLA-restricted cytotoxic T-cell epitopes using synthetic HBV peptides and demonstrated sequence-specific peptide recognition by CD8-positive T cells. HLA restriction, immunodominance, and functional response vary with the exact residue range and sequence.

• HBV-specific CTL assays
• HLA peptide-binding studies
• viral epitope mapping
• T-cell stimulation controls
• sequence-dependent immune-response studies

For antigenic or viral peptides, HLA restriction, cellular response, and immunological activity should not be inferred solely from the source protein name; the exact sequence, residue numbering, strain or genotype, and experimental system should be considered. For labeled or otherwise modified variants, the modification may also affect binding or assay behavior.
