Dear colleagues, can you please recommend a pan caspase activity assay/kit to be used for cell lysates (rather than in whole cells in situ)?
Many thanks,
Joanna
Hi Joanna
Selectivity assays for caspases can be initiated with purified enzyme

Thanks. I am not sure if Ab65616 can be used on the cell lysates though?
