Flow cytometric analysis of a PI-stained CD28 transfected murine T-cell hybridoma. DWT6.11 cells were seeded for 8 hours in a 24-well plate in the presence of the indicated MoAbs as described in the Materials and Methods. (A) PI staining versus the number of nuclei in one representative experiment. Numbers above histograms indicate the percentage of apoptotic nuclei. (B) Results are presented as averaged percentage (±standard deviation [SD]) of subdiploid nuclei obtained from six independent experiments.
