Fluorescent DNA stains are commonly used to stain DNA in bacteria or eukaryote cells.JW1 Methyl proamine is a cell-permeable blue-emitting DNA stain that binds selectively to AT-rich regions. It provides a brighter alternatives to existing dyes, such as DAPI and Hoechst 33258 for fixed- and live-cell fluorescent staining of DNA and nuclei in cells. The methyl proamine is excited by ultraviolet light and emits blue fluorescence at 460-480 nm.
