Description

DAPI (4',6-Diamidino-2-Phenylindole, Dilactate), a blue fluorescent nucleic acid stain, preferentially binds dsDNA and associates with the minor groove AT clusters. The molecular weight for DAPI is 457.5.  Association of DAPI with dsDNA increases fluorescence approximately 20-fold, with an emission maximum of 460 nm. The increase in fluorescence is believed to be due to displacement of water molecules from the minor groove and DAPI. DAPI can also bind RNA and emits at a longer wavelength of 500 nm, with only a 20% increase in fluorescence.

DAPI is a popular nuclear stain for identification of cell cycle and specifically stains nuclei but not cytoplasm. The dilactate form is more water soluble compared to the dihydrochloride form.

DAPI can be excited by a UV laser, xenon, or a mercury-arc lamp.

Application Notes

Protocols for Counterstaining with DAPI:

Immunofluorescence Staining
Note: Cells may be fixed by method of choice, such as with 4% paraformaldehyde. DAPI staining is done after staining for other markers. Fixation and permeabilization of cells is not necessary to counterstain with DAPI.

1. Fix cells using method of choice.
2. Incubate the cells with phosphate buffered saline (PBS) for 15 minutes.
3. Dilute the DAPI solution (we recommend to 300 nM) with PBS. Remove excess PBS from the slide and cover with DAPI solution, making sure the cells are completely covered.
4. Incubate for up to 5 minutes. Rinse the slide several times to remove all free DAPI. It is recommended to use a mounting medium with antifade reagent to reduce fluorescence quenching. The slide is ready to view under the microscope with appropriate filters.


Nuclear Staining for Flow Cytometry
Note: Cells may be fixed with 4% paraformadehyde or absolute ethanol.

1. Fix cells with absolute ethanol or 4% paraformaldehyde.
2. Centrifuge, discard the supernatant, and add 5 ml of PBS, allowing cells to rehydrate for 15 minutes.
3. Dilute the DAPI to 3 µM (recommended) in staining buffer (such as BioLegend's FOXP3 Perm Buffer, Cat. No. 421402).
4. Centrifuge cell suspension from step 3 above, discard supernatant, and add 1 ml of DAPI solution; then incubate at room temperature for 15 minutes.
5. Analyze by flow cytometry using an instrument with appropriate lasers.
