We have developed a non-radioactive flow-cytometry assay to monitor and quantify the target-cell killing activities mediated by cytotoxic T lymphocytes (CTLs). This flow-cytometry CTL (FCC ...

An untreated group was also included. In secondary CTL assays, PIC vaccination resulted in remarkably high activity, with 91 ± 5% specific lysis observed at a 25:1 effector-to-target (E ...
