CellfreeSystemfortheexaminationofapoptoticactivity
IntroductionIn our lab we use the term 'cell-free system' when we talk about the examination of apoptotic activity in cytoplasmic extracts. The cytoplasmic extracts may be prepared from cells which were treated in culture with an apoptosis-inducing agent or from untreated cells. In the latter case, apoptotic activity can be induced by addition of apoptotic stimuli (such as recombinant active caspases or......阅读全文
