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

什么是水活度（Water－Activity）
水活度被定义为当前可用“自由水”的量，和水分含量没有直接的对比关系，水活度值范围在0(绝对干燥)和1（100%相对湿度）之间。当物质与环境空气发生水分交换活动会在表面形成对微生物生长的理想条件，这样会影响微生物的稳定性。水活度同时也是影响食品中化学反应的重要因素。
