AnIntegrativeProcedureforApoptosisIdentificationandMeasurement
IntroductionApoptosis is a normal physiological phenomenon put forward by Kerr [1]. It plays an important role in embryonic development, maintenance of tissue homeostasis and pathology, and therefore has become a hotspot of activity in biomedical fields. To date, many methods to detect apoptosis have sprung up, including morphological identification, DNA ladder observation and DNA content and cell cycle analysis. How......阅读全文
