DAPI Nuclear Stain Solution: Practical Protocol
2026-08-17
DAPI (4',6-Diamidino-2-Phenylindole) Nuclear Stain Solution provides a ready-to-use fluorescent DNA binding dye for nuclear visualization in fixed or membrane-compromised cells. It supports fluorescence microscopy and flow cytometry workflows for cell viability assessment and apoptosis-related nuclear evaluation, but its weak cell permeability makes it unsuitable as a routine live-cell imaging stain.
