DAPI Staining Protocol
Prepare the following solutions:
(To determine the amount needed for your experiment, please note that one tube of Solution 1 will yield a total of 100mL of working solution, at a final concentration of 0.5ug/mL.)
5 μL DAPI (10 mg/ml solution)
995 μL PBS
*Solution is viable for one month if stored at 4° in the dark
Solution 2 (working solution):
10 μL of Solution 1
990 μL PBS
Add Solution 2 (working solution) to your tissue/cells and incubate at room temperature for 1- 5 minutes.
Rinse 2X with PBS.
Mount coverslip with Shur/Mount, Prolong or comparable antifade medium.
Seal coverslips (if necessary) with Valap or nail polish.**
**Try to avoid nail polish if are visualizing GFP, as the additives in nail polish tend to quench the signal.
