DAPI and Hoechst are classic popular nuclear counterstains for use in all fluorescent cell and tissue techniques. The blue fluorescence is vivid contrast to green, yellow, orange, red, far red and NIR fluorescent probes and labels.
Optimized for analysis of physiologically relevant concentrations (pg/mL levels) of specific cytokine proteins in tissue culture supernatants, EDTA plasma, and serum samples
Used to stain nucleic acids in fixed cells. BD Pharmingen™ DRAQ7™ is also used for cell cycle analysis by DNA content, nuclear visualization, or discrimination of nucleated cells from debris or neucleated cells.
Thermo Scientific Pierce DAPI Nuclear Counterstains are high-purity forms of diamidino-2-phenylindole dye for fixed-cell, fluorescent staining of DNA content and nuclei for cellular imaging techniques.
