How should D9542, 4´,6-Diamidino-2-phenylindole dihydrochloride (DAPI), be dissolved?
This product is soluble in water at 20 mg/mL, but may require heat. DAPI does not dissolve readily in PBS, 0.1 M phosphate, or 0.1 M Tris (pH 7).
How should D9542, 4´,6-Diamidino-2-phenylindole dihydrochloride (DAPI), be stored once in solution, and for how long would it be good?
Solutions stored in the dark at room temperature have been stable for 2-3 weeks, but solutions exposed to light for the same time period have shown considerable degradation. At 1 mg/mL, solutions are stable in the dark at 2-8 °C for several weeks. For long-term storage, the solutions can be divided into aliquots and stored at -20 °C.
Aside from the applications described on the product page, how is D9542, 4´,6-Diamidino-2-phenylindole dihydrochloride (DAPI), used?
DAPI is used as a nuclear counterstain in our FISH protocol at 2 μg/mL in antifade mounting media. DAPI can also be used as a vital dye to stain mature pollen grains (0.5 μg/mL). DAPI can bind to RNA, but its selectivity for DNA over RNA is high. It appears that DAPI uses an intercalating binding mode with RNA that is AU selective (Biochem., 31, 3103 (1992)). Selectivity of DAPI for DNA over RNA is greater than that shown by ethidium bromide and propidium iodide (Nucleic Acid Research, 6, 3535 (1979))

What is the stability of D9542, 4´,6-Diamidino-2-phenylindole dihydrochloride?
Product D9542, 4´,6-Diamidino-2-phenylindole dihydrochloride has a stability of 3 years as supplied. The product in solution is also stable in the dark at 4°C and showed no signs of degradation after three weeks at room temperature in the dark. Material exposed to light showed significant degradation. We have developed an HPLC method for our DAPI products that shows reassay results from July 2012 for lots that were originally released for sale in December 2008, for both D9542 (DAPI dihydrochloride) and D9564 (DAPI dilactate).
