Localization of hepatitis B surface antigen epitopes
present on variants and specifically recognized by antihepatitis B surface antigen monoclonal antibodies.
Our aim was to investigate whether these deamidated peptides are CD antigen epitopes
that are more specific for circulating antibodies than native peptides.
Apthera's licensed technology is based on the use of single immunostimulatory peptides, such as E75, and peptide combinations to activate multiple "killer" T-cell clones against multiple tumor antigen epitopes
