NucPO-1 (434/456)

PODi-1 (Oxazole Blue Homodimer, also known as POPO^®-1) is a blue fluorescent carbocyanine dimeric dye. PODi-1 is a cell-impermeant nucleic acid stain that is nonfluorescent in the absence of nucleic acids but exhibits a multiple fluorescence enhancement upon binding to dsDNA.

The bright fluorescence signal and low background make PODi-1 ideal for staining nucleic acids on microarrays, as well as for nuclear and chromosome counterstaining in multicolor fluorescence labeling experiments.
