Effect of phosphatidyl inositol 3-kinase inhibitors on viability of monocyte-derived dendritic cells

Condition	Cell viability (%)
Immature dendritic cells	100
Mature dendritic cells	100
Wortmannin 0·03 μm	100
Wortmannin 0·1 μm	100
Wortmannin 0·3 μm	100
Wortmannin 1 μm	100
LY294002 1 μm	100

Monocyte-derived DC were treated with the indicated concentration of phosphatidyl inositol 3-kinase inhibitors for 24 hr and their viability was determined by dye-exclusion. Results shown are % viability from a representative donor and viability was monitored in all experiments.
