Effect of alanine point substitutions of peptide G4 on stimulation of clone 4 (A) and clone 9 (B). Bars represent the mean (SEM) of triplicate counts per minute (CPM) obtained for each test. Curves shows interferon γ (IFN-γ) secretion (detection limit of the assay was 15 pg/ml in (A) and 30 pg/ml in (B)). (C) Effect of alanine point substitutions of peptide G4 on interleukin (IL)-10 and IL-4 secretion of clone 4. The lower detection limit of the IL-10 assay was 1 pg/ml and for IL-4, 1.25 pg/ml. APC, antigen presenting cells.
