CytoALL™ DNA Red 600

The common fluorescent DNA probes (such as DAPI, Hoechst or SYBR® Green) predominantly stains the DNAs in nuclei. There is a unmet need for a universal DNA probe that can stain the total cellular DNAs in live cells. CytoALL™ DNA Red 600 has been developed to stain all the DNAs in live cells. CytoALL™ DNA Red 600 is a DNA-selective, cell permeable dye that stains all DNA contents including nuclei and mitochondria in live cells. The staining is simple and robust. It only requires a single step of incubating cells in the presence of CytoALL™ DNA Red 600. The cells can be viewed with a TRITC filter set, allowing it to multiplex with various other fluorescent imaging probes. AAT Bioquest also offers a variety of DNA probes for staining nuclei (such as Nuclear Blue™, Nuclear Green™ and Nuclear Red™) and MitoDNA™ for selective staining of mitochondrial DNAs (mtDNA).

The fluorescence response of CytoALL™ DNA Red 600 (20 µM) was evaluated in HeLa cells before and after treatment with DNase (2 units/reaction) at 37°C for 1 hour. Fluorescence intensities were monitored using a fluorescence microscope equipped with a Cy3 filter.
