Efficacy of positional scanning combinatorial library based predictions for 3 HLA class I alleles. The percent of peptides scoring within a specified percentile range that bind A*3001, A*3201 or B*1501. Peptides were scored using the corresponding combinatorial library matrix. Peptides were then assigned a percentile score indexed to the percentile associated with 9-mer peptides derived from vaccinia with the same matrix score. About 60,000 9-mers derived from the vaccinia WR sequence were scored to develop the indices.
