Consensus differences of HIV-1 Gag between 454 and Sanger clone-based sequencing methods overlapped with the functional of immunogenic sites in individuals.

a: patient IDs are from a cohort of the Pumwani Sex Worker in Nairobi, Kenya; b: positions are referred to HXB2 gag gene; c: CTL epitopes are derived from the best-defined CTL epitope summary (HIV Molecular Immunology 2009, Los Alamos National Laboratory, USA). The differences between consensus sequences are shown in bold.
