A total of 105 responder cells and 105irradiated (2,000 cGy) stimulator cells obtained from DLA-nonidentical unrelated dogs were cultured per well either in the absence or the presence of increasing concentrations of CTLA4Ig or the control peptide L-6. 3H-thymidine incorporation was determined after 6 days of culture. Responses are presented as the mean cpm of triplicate experiments. CTLA4Ig was tested in 2 separate experiments.
