Analysis of nuclear morphology and DNA degradation.

(A) Epifluorescence photomicrographs of isolated blood PMNs fromCD18^+/+ mice orCD18^−/− mice stained with acridine orange 4 hours after the onset of culture. Results are representative of 3 independent experiments. (B) Agarose gel of low-molecular-weight DNA of isolated blood PMNs fromCD18^+/+ orCD18^−/− mice 4 hours after the onset of culture. Results are representative of 3 independent experiments.
