Hoechst fluorescent dye
NettetINTRODUCTION. Fluorescence microscopy provides a powerful tool for imaging molecular components in living cells. Specific molecular components can be efficiently labeled by a combination of three methods: (1) chemical transfection of GFP-fusion constructs, (2) staining of chromosomes with the DNA-specific, fluorescent dye Hoechst 33342, and … NettetHoechst 33342 nucleic acid stain is a popular cell-permeant nuclear counterstain that emits blue fluorescence when bound to dsDNA. This dye is often used to distinguish …
