DRAQ5™ Fluorescent Probe


DRAQ5™ Fluorescent Probe is a far-red DNA stain for live or fixed cells and easy multiplexing with other fluorophores, such as cells expressing green fluorescent protein (GFP) fusion proteins.

DRAQ5™ Fluorescent Probe is a far-red DNA stain for fluorescent cellular imaging applications with live or fixed cells. Because of its far-red excitation and emission, the DRAQ5 Stain can be multiplexed with many other fluorophores. It is commonly chosen to counterstain nuclei and measure DNA content in cell proliferation studies involving cells expressing green fluorescent protein (GFP) fusion proteins. DRAQ5 Fluorescent Probe is compatible with many existing protocols across a wide range of instrumentation platforms.
