Fas ligand induction to promote apoptosis assessed by RT-PCR at 4 hours.

<p>Cells were grown in culture media alone, stimulated with srh CD154 at 1 µg/ml or srh FasL at 50 ng/ml for 4 hours. (a) densitometry scanning data for FasL PCR gels at 4 hours. n = 4+/− standard error of the mean. (b i) a representative FasL PCR gel and (b ii) the corresponding β-actin gel. *p<0.05, **p<0.01 as compared to untreated controls.
