Activation of monocytes leads to down-regulation of caspase-8/FLICE activity

Treatment	% Inhibition of fluorescence*
LPS 25 ng/ml	86.0  ±  0.4
LPS 250 ng/ml	86.6  ±  0.5

*Cell lysates from LPS-treated cells were incubated with IETD-AFC. Free AFC accumulation was monitored by using a fluorometer with 400-nm excitation filter and 505-nm emmision filter. Percent inhibition of fluorescence was calculated in comparison to untreated control samples and represents the mean ± SD of samples done in triplicate.
