Nucleic Acid Binding Dyes

A membrane-permeable DNA dye, excellent for staining both gram positive and gram negative bacteria. Stained cells can be detected by fluorescence microscopy or flow cytometry.

A patented green fluorescent nucleic acid dye with features that are ideal for applications such as qPCR, HRM®, LAMP, and digital PCR.

DODC (DiOC₂(5)) has been reported to bind to triplex DNA as well as dimeric hairpin quadruplex DNA (1). Binding of the dye to triplex DNA quenches the fluorescence of the dye and red-shifts the dye absorption peak.

DiSC₂(5) (3,3′-Diethylthiadicarbocyanine, iodide) binds to DNA-DNA or PNA-DNA duplexes with a large blue-shift of the absorption spectrum. Binding of the dye to PNA-DNA hybrid, in particular, blue-shifts the dye absorption spectrum by as much as 115 nm, offering a visual method to detect nucleic acid hybridization (1,2).

7-AAD (7-aminoactinomycin D) is a membrane-impermeant fluorescent DNA binding dye that is useful for live/dead discrimination and cell cycle profiling by flow cytometry.

A photo-activated fluorescent nucleic acid binding dye used to selectively and covalently label dead cells in the presence of live cells for viability PCR, fluorescent microscopy, and flow cytometry.

PAGE GelRed® is a non-toxic, non-mutagenic red DNA gel stain specifically formulated to stain DNA in polyacrylamide gels. PAGE GelRed® can be imaged using a 254 nm UV transilluminator with an ethidium bromide filter.

6X GelRed® Prestain Loading Buffer is a DNA gel loading buffer containing GelRed® for one-step fluorescent staining and gel loading of DNA.

A revolutionary antifade mounting medium optimally formulated for preserving fluorescence of our CF® dyes and other fluorochromes. Available with or without DAPI.

Thiazole Red, also known as TO-PRO®-3, is a cell-impermeant, high-affinity far-red nucleic acid stain.

GelGreen® is a sensitive, non-mutagenic and environmentally safer green fluorescent DNA gel stain.
