In Vitro	Bz-423 induces a larger superoxide response in Ramos cells, and causes rapid death of Ramos B cells. Bz-423 activates Bax and Bak, but does not activate ASK1/JNK in Ramos cells. In Ramos cells Bz-423-induced superoxide leads to Bax and Bak activation via changes in Mcl-1 expression and functional activation of BH3-only proteins[1]. Bz-423 rapidly increases superoxide levels in MEFs within 1 h and the magnitude of the increase is concentration-dependent. Bz-423-induced apoptosis dependents upon superoxide[2].
Kinase Assay	To detect ASK1 activity, inactive GST-MKK6 (0.1 mg) is incubated (15 min, 25°C) with immunoprecipitated ASK1 in kinase assay buffer. Subsequently, GST-p38α (0.5 µg) is added to this reaction and incubated (15 min, 25°C) followed by detection of phospho-GST-p38 via immunoblot.
