Epitope Subtype C
Variant Subtype C
Method CD8 T-cell Elispot - IFNy, HLA binding, Intracellular cytokine staining, Sequence, Tetramer binding
Note The C clade variant, NPPIPVGeIY, is also the major B clade form of epitope NY10. This NY10-260E variant binds to HLA-B*3105 10x less well than the wt and is 3x less stable.
