About NucSpot 680/700

NucSpot 680/700 has an excitation peak at 683 nm and an emission peak at 720 nm. NucSpot Nuclear Stains are cell membrane-impermeant, nuclear-specific counterstains. They have minimal fluorescence until they bind to DNA and can be used for no-wash nuclear staining. They can also be used for selective staining of dead cells in unfixed cell cultures for analysis by flow cytometry or fluorescence imaging.
