LUCS 13 is a cell-permeant nucleic acid stain that exhibits green fluorescence upon binding to nucleic acids. The stain has a high fluorescent yield and a structure identical to SYTO™13 stain.

LUCS 13 is used to stain both DNA and RNA in live and dead eukaryotic cells as well as Gram-positive and Gram-negative bacteria. The dye is excited by the blue laser at 488 nm. Its fluorescence emission is detected in the fluorescein channel with a peak at 509 nm when bound to DNA and 514 nm when bound to RNA.

The dye can be used in simultaneous labeling with cell-impermeant nuclear markers, such as YoDi-3, to evaluate cell viability using fluorescence microscopy and flow cytometry.

Human blood smear stained with green fluorescent nuclear stain LUCS13 and antibodies to neutrophil myeloperoxidase. Human blood smear stained with green fluorescent nuclear stain LUCS13 (x4010) and antibodies to neutrophil myeloperoxidase. Antibodies were labeled with red fluorescent dye sulfo-Cyanine5 using the Lumiprobe sulfo-Cyanine5 antibody labeling kit (3321-x).
Live RAW 264.7 cells stained with cell-penetrating nuclear dye LUCS 13 (0.5 µM, x4010, analog of SYTO™13) and PKH26 cell membrane labeling kit (x3201). Cells were counterstained with the nuclear dye Hoechst 33342.
