Protocol for detection of ferroptosis in cultured cells

Summary: Mammalian cells can die by apoptosis or by one of several non-apoptotic mechanisms, such as ferroptosis. Here, we present a protocol to distinguish ferroptosis from other cell death mechanisms in cultured cells. We describe steps for seeding cells, administering mechanism-specific cell death inducers and inhibitors, and measuring cell death and viability. We then detail the use of molecular markers to verify mechanisms of cell death. This protocol can be used to identify and distinguish ferroptosis in 2D and 3D cultures.For complete details on the use and execution of this protocol, please refer to Ko, et al. (2019),1 Magtanong, et al. (2022),2 and Armenta, et al. (2022).3 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
