We applied an enzyme-linked immunospot (ELISPOT) assay for the detection and
quantification of blood-derived CD8+ T cells recognizing peptide antigens presented by HLA-
A2. 1. CD8+ T lymphocytes were isolated from peripheral blood and were stimulated for 40 h
with peptide-loaded A2. 1-positive 0.174× CEM. T2 cells. Tumor necrosis factor α (TNF-α)
secreted by single T cells in response to antigen contact was trapped on nitrocellulose
membranes precoated with anti-TNF-α antibodies and was then immunochemically …
