Effect of concanamycin A on cytotoxicity mediated by PE-9 cells against Fas+ and Fas− targets. PE-9 cells were tested for lytic activity against various 51Cr-labeled targets exactly as described in Fig 3, except for the addition of concanamycin A. The cytotoxicity assay depicted in A to F was performed in a similar fashion as described for the respective panels in Fig 3.
