Live-Cell High-Throughput Screen for Monitoring Autophagy Flux.

Autophagy is a cellular process implicated in the renewal of cellular components and the maintenance of cellular hemostasis and therefore associated with various types of diseases. In addition, autophagy belongs to the stress response pathways and is frequently activated by chemical compounds harboring characteristics of cell toxicity. High-throughput screens analyzing autophagy flux are therefore applied in both, the field of compound identification for targeting autophagy and compound characterization for analyzing compound toxicity. In this chapter, we describe a live-cell, fluorescent-based, high-throughput screening method in 384-well format for the fast and accurate measurement of autophagy flux over time suitable for academic research, pharmacological applications, and drug discovery.
