Sensitivity of bifunctional cultures to low levels of recognized antigens. TIL 5 TCR-transduced cultures were cocultured for 24 hours in a 1:1 ratio with T2 cells loaded with decreasing concentrations of peptide. Supernatants were collected and the amount of interferon-γ released was measured using ELISA. Values are the average of triplicate wells. Asterisk (*) indicates value was greater than maximum point on standard curve.
