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.

In order to know if the fluorescent pattern was not an artifact, we performed a DAPI stain to see the nuclei of parasites into the PRBC (Fig.
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.
When there were fewer than 50 cells discernible by DAPI stain, then all cells were examined, and the MYB FISH signals were recorded.
DAPI stain is the most widely used fluorochrome to stain nuclear DNA in fluorescence microscopy.

Treatment of H37Rv-infected neutrophils with GSH-enhancing agents did not result in any loss in the viability of neutrophils as evident from the quantification of DAPI stained cells (Figure 1(b)).
Lasers used were the Coherent UV with excitation lines of 351 and 361 nm to visualize DAPI stained nuclei and a Uniphase argon laser line at 100% in the Acousto-Optical tuneable filter for the visualization of the Al-lumogallion complex.
