"A series of 15-mer peptides overlapping each other by 10 amino acids and a series of 9-mer peptides overlapping each other by 8 amino acids covering the HPV16 E6 protein have been described (20). To define the minimal and optimal amino acid sequences of the CD8 T-cell epitope, 8-mer, 10-mer, 11-mer, and homologous peptides (see Table 1) were synthesized as needed (CPC Scientific, Inc., San Jose, CA)."

"The combinatorial library (CPC Scientific) was composed of the sequence GXXGXXGXXGXX (X = cysteine, aspartic acid, or glutamic acid; G = glycine) and synthesized onto TentaGel Macrobeads..."
