DAPI Solution (1 mg/mL)

DAPI (4',6-Diamidino-2-Phenylindole) is a blue-fluorescent DNA stain that binds strongly to DNA, with fluorescence increasing substantially upon binding. It is weakly cell-permeable, preferentially staining cells with compromised membranes (e.g., dead, apoptotic, or fixed cells), and is commonly used for nuclear visualization, viability assessment, and apoptosis detection.

This product is supplied as a 1 mg/mL solution in DMSO. Dilute to the desired working concentration before use. Stained samples can be analyzed by fluorescence microscopy or flow cytometry.
