An Annexin V-FITC-Propidium Iodide-Based Method for Detecting Apoptosis in a Non-Small Cell Lung Cancer Cell Line

Abstract

Annexin V and propidium iodide staining is widely used for determining the cellular death through apoptosis. In the presence of Ca2+ ions, annexin V has a strong binding affinity for phosphatidylserine, a membrane phospholipid that during apoptosis is translocated from the inner side of the cell membrane to its outer side. On the other hand, propidium iodide has ability for DNA binding and it can only enter into necrotic or late apoptotic cells. This chapter describes a commonly used method for detection of apoptosis in a non-small cell lung cancer cell line using annexin V and propidium iodide dye. We describe the detection of different stages of apoptosis in the A549 lung cancer cell line treated with dihydroartemisinin (DHA). This apoptosis detection method can be used to determine the efficacy of different kinds of drugs on cultured cancer cell lines.
