DAPI stain

DAPI stain

4'6-diamidino-2-phenylindole·2HCl; a sensitive fluorescent probe for DNA used in fluorescence microscopy to detect DNA in yeast mitochondria, chloroplasts, viruses, mycoplasma, and chromosomes; DNA is visualized in vitally stained living cells and after cells are fixed in formaldehyde.

When there were fewer than 50 cells discernible by DAPI stain, then all cells were examined, and the MYB FISH signals were recorded.
Another 10 ul of haemolymph suspension was placed on a glass slide and stained with DAPI stain (4, 6-diamidino-2-phenylindole) (Kapuscinski, 1995) to observe morphology of the nucleus and to confirm appearance (shape and structure) of nucleus of haemo-lymphocytes by using fluorescent microscopy.
2); the nucleus contained very high density of granules with blue fluorescence color, but DAPI stain could not stain cytoplasm.

DAPI stain is the most widely used fluorochrome to stain nuclear DNA in fluorescence microscopy.
I'm impressed by the compactness and conciseness of the DAPI stain and the exclusion of your probe.
The DAPI stains only the nuclei, allowing enumeration of sperm with relative ease (see Sakaluk 1984 for details of a similar method using Hoechst 33258 stain).
