Invitrogen™ Hexidium Iodide

The nucleic acid stain, hexidium iodide is permeant to mammalian cells and selectively stains almost all gram-positive bacteria in the presence of gram-negative bacteria. Hexidium iodide exhibits excitation/emission maxima of ∼518/600 nm upon binding DNA. Generally, both the cytoplasm and nuclei of eukaryotic cells show staining with hexidium iodide.
