| 1. A method of detecting T lymphocytes that are specific for a nominal antigen, comprising:
culturing a sample containing peripheral blood mononuclear cells with a nominal antigen;
adding to said sample an inhibitor of cytokine secretion;
permeabilizing said cells;
adding to said sample at least one cytokine-specific antibody and at least one T lymphocyte subset-defining antibody; and
then
flow cytometrically detecting the intracellular binding of said cytokine-specific antibody by cells in the defined T lymphocyte
subset.
