"Peptides 20 amino acids in length spanning the HA and NA proteins of the A/Anhui/1/2013 (H7N9) virus were generated with 15-amino-acid overlaps, resulting in the synthesis of 110 HA peptides and 90 NA peptides synthesized at >90% purity (CPC Scientific). A small number of peptides were synthesized at >70% purity, following multiple synthesis and purification attempts. A poly(K) linker was added to each peptide to increase solubility and to improve the binding orientation of peptides to the Hydrogel slides."

"The tandem peptide library used in this work was synthesized via standard FMOC solid-phase peptide synthesis and purified by high-performance liquid chromatography at the MIT Biopolymers Core, Tufts University Core Facility or CPC Scientific, Inc."

"Epitope mapping studies were carried out using an overlapping series of synthetic peptides (CPC Scientific, CA) designed based on the primary sequence of OPN. Peptides corresponding to the region 143-172 of human OPN are listed below [..]"

"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..."
