High-Speed Phenotypic Profiling Using a Next Generation High-Content Imaging Platform With AI-Enabled Image Analysis

High-content imaging plays a pivotal role in modern drug discovery by enabling the simultaneous capture of multiple cellular features—offering a more comprehensive view of cellular responses to perturbations than single-parameter assays. To advance this capability, we developed the next-generation ImageXpress® HCS.ai High-Content Screening System (Molecular Devices), featuring a fully reengineered hardware and software platform. Enhanced x, y, and z stage movement and adaptive autofocus deliver greater throughput, while a state-of-the-art optical light path—including optimized illumination and a high-quantum-efficiency camera—enables reduced exposure times, lower background, and a significantly improved signal-to-noise ratio.
