Figure 4.
(a) Western blot demonstrating expression of the 55 000 MW pro-caspase 8 (FLICE) protein by peripheral blood lymphocytes harvested at various time intervals from a MLR assay; α-tubulin was also visualized to demonstrate constant protein loading. (b) Results from a fluorimetric assay of the enzymatic activity of caspase 8. Each column represents the mean of duplicate determinations; the error bars show the SEM. (c) Western blot demonstrating expression of the 55 000 MW FLIP protein by peripheral blood lymphocytes harvested at various time intervals from a MLR assay; α-tubulin was also visualized to demonstrate constant protein loading.
