Nucleic Acid Binding Dyes

Biotium’s hardset antifade mounting medium with NucSpot® 640 far-red nuclear counterstain.

Unique hardset antifade that quenches lipofuscin autofluorescence. Choose with mounting medium with DAPI, far-red NucSpot® 640, or without nuclear stain.

A photo-reactive DNA-binding dye typically used in viability PCR (v-PCR) of microorganisms like bacteria, viruses, and fungi.

Hoechst dyes are cell membrane-permeant, minor groove-binding blue fluorescent DNA stains. Hoechst dyes are widely used in cell cycle and apoptosis studies as nuclear counterstains.

Oxazole Blue, also known as PO-PRO™-1, is a blue-fluorescent, cell-impermeant nucleic acid stain that can be used to stain dead or fixed cells.

An improved alternative to 7-AAD showing less bleed-through fluorescence in the PE-Texas Red® channel. Ideal for selective detection of dead cells by flow cytometry.

6X DNA loading buffer that includes ultra-sensitive, non-toxic GelRed® dye.

Ultrapure molecular biology grade agarose pre-coated with GelGreen® Nucleic Acid Gel Stain for convenient and safer preparation of precast gels.

Ultrapure molecular biology grade agarose pre-coated with GelRed® Nucleic Acid Gel Stain for convenient and safer preparation of precast gels.

Wet-set antifade mounting medium for preserving fluorescence of our CF® dyes and other fluorochromes, in a dropper bottle for easy dispensing.

MB (methylene blue) acid can be conjugated to peptides, proteins, drugs, polymeric materials and biomolecules with primary amine groups.  The conjugate will have a blue color and be able to complex with nucleic acids.

Cell membrane-impermeant, nuclear-specific counterstains. Suitable for fixed cells or staining dead cells in live cultures.

Thiazole red homodimer (TRhD), also known as TOTO®-3, is a cell-impermeant, high-affinity, far-red fluorogenic nucleic acid stain.

No-wash, fluorescent DNA nuclear stains dyes with low toxicity for long-term live cell imaging or fixed cell staining. Choose green or far-red fluorescence.

Oxazole Yellow, also known as YO-PRO®-1, is a green-fluorescent, cell-impermeant nucleic acid stain that can be used as a early marker of apoptosis.

TO Iodide, also known as TO-PRO®-1, is a green fluorescent, cell-impermeant nucleic acid stain that can be used to stain dead or fixed cells.
