Effect of different doses of the anti-CD18 MoAb MEM48 on the GM-CSF–stimulated neutrophil-mediated Lym-1 antibody-dependent cytolysis. 51Cr-labeled Raji cells were at 2 × 104. The neutrophil-Raji cell ratio was 20:1. Lym-1 and GM-CSF were at 10 μg/mL and 1 ng/mL, respectively. The incubation time was 14 hours. The two curves show the results obtained with neutrophils from two donors.
