Nuclear Stains & DNA/RNA Dyes
We offer a selection of nuclear stains for live, fixed, or dead cells in multiple colors. Visit our Cellular Stains Technology Page to learn more.
NucSpot® Live Cell Nuclear Stains
NucSpot® Live Cell Nuclear Stains are cell-membrane permeable DNA dyes that specifically stains nuclei in live or fixed cells. They have excellent specificity for DNA without the need for a wash step, and they have low toxicity for live cell imaging.
