"The PepCan peptide mixture will contain four HPV 16 E6 peptides: E6 1-45 (Ac-MHQKRTAMFQDPQER PRKLPQLCTELQTTIHDIILECVYCKQQLL-NH2 (SEQ ID NO:2)), E6 46-80 (Ac-RREVYDFAFRDLCIV YRDGN PYA VCDKCLKFYSKI-NH2 (SEQ ID NO:3)), E6 81-115 (Ac-SEYRHYCYSLYGTTLEQQYNK PLCDLLIRCINCQK-NH2 (SEQ ID NO:4)), and E6 116-158 (Ac-PLCPEEKQRHLDKKQRFHNIRGRWT GRCMSCCRSSRTRRETQL-NH2 (SEQ ID NO:5)) (U.S. Pat. No. 8,652,482). Commercially produced cGMP-grade peptides (CPC Scientific, San Jose, Calif.) will be examined.. CANDIN was dialyzed before use to remove a small amount of solvent (0.4% phenol) using Slide-A-Lyzer G2 Dialysis Cassette (Thermo Scientific, Rockford, Ill.). LCs were prepared as described above, and one million LCs each were treated with CANDIN (150 μl/ml), four current good manufacturing practice-grade HPV16 E6 peptides [E6 1-45, E6 46-80, E6 81-115, and E6 116-158 (referred to as “peptides” hereafter); 10 μg/ml/peptide; made by CPC Scientific, Sunnyvale, Calif."

"ASY*-FITC was synthesized using good manufacturing practice (GMP) methods (CPC Scientific, Inc.). Stability was evaluated on high-performance liquid chromatography (HPLC) and mass spectrometry. Aliquots of peptide (0.8 mg) were stored at −20 °C as lyophilized powder in single-use amber vials for protection from light."

"To define the minimal and optimal amino acids sequences of the CD8 T-cell epitope, 8-mer, 10-mer, 11-mer, and homologous peptides were synthesized (CPC Scientific, Inc, San Jose, Calif.). All peptides were dissolved in small amounts of dimethylsulfoxide (˜50 μl), diluted to 5 mM with phosphate buffered saline, and kept frozen at −80° C. until final dilution for their use in the assay... Commercially produced cGMP-grade peptides (90% purity; CPC Scientific, San Jose, Calif.) is examined. Their safety for human use is ensured, in accordance with FDA requirements, by testing 14-day sterility (USP <71>), testing pyrogens, describing appearance and identity, analyzing amino acids, determining impurities by HPLC, assessing H2O content and net active peptide, and describing any organic solvents (each peptide to be assessed individually as per the FDA).
