DAPI dilactate is essentially the same as DAPI HCl (#6937) except in their counter ions. The dilactate counter ions make the dye more water soluble. DAPI shows blue fluorescence upon biniding DNA and also can be excited by UV. The blue fluorescent DAPI stain apparrantly associates with the minor groove of dsDNA, preferentially binding to AT clusters. DAPI is an excellent nuclear counterstain, showing a distinct banding pattern in chromosomes. It is also used for cell-cycle studies and mycoplasma detection. DAPI is a very sensitive dye that could be used to detect single nucleic acid molecules. DAPI has been shown to detect a single DNA molecule in solution, and to detect femtograms of DNA in single cells and chloroplasts.
