Abstract
A new class of red-emitting, fluorescent [8,9]benzophenoxazine dyes are provided that are useful for staining nucleic acids in a variety of contexts, including in solutions, in electrophoretic gels or other matrices, in blotting experiments and in assays employing intact, live cells. The new dyes are brighter and permeate cells faster than currently available red-emitting live-cell nucleic acid stains.
