  • a Peptides spanning a junction (-) between two conserved regions in the HIVconsv immunogen, thus creating a novel epitope not present on HIV-1-infected cells.

  • b LANL-HSD, Los Alamos National Laboratory HIV Sequence Database; SB, strong binder; WB, weak binder; NA, not applicable; −10logP, negative decadic logarithm of P, the probability that the identification is a random event.
