Cytotoxic T lymphocytes (CTL) are a subset of lymphocytes that have the ability to lyse target cells bearing specific antigens. To assess the functionality of CTLs, target cells previously primed to contain radioactive chromium within the cell membrane are incubated with patient or control lymphocytes. Lysis of the target cells by the CTLs is measured by the amount of chromium released into the supernatant.
