Protocol for induction and study of DNA double-strand breaks in mammalian cells using PALM microdissection and expansion microscopy

Summary: We present a protocol to induce localized DNA double-strand breaks (DSBs) in mammalian monolayer cells, using the PALM MicroBeam microdissector, followed by high-resolution visualization through expansion microscopy (ExM). We describe steps for laser microirradiation, immunostaining, and ge...
