CRA results of PS-SCL screen of TCC 3-3F4.

Separate aliquots of T2 cells were pulsed with one of 180 mixtures (50 μg/mL) that make up the PS-SCLs and incubated with 3-3F4 cells as described in “Materials and methods.” All experimental points were obtained at the same time, and results shown represent the average of 2 experiments done on different days. The native amino acid at each position of the nonamer pp65_495-503 peptide is indicated by a cross-hatched bar for each positional sublibrary graph.
