Nuclear Stains & DNA/RNA Dyes

A membrane-impermeant nucleic acid intercalator. The dye is commonly used to selectively stain dead cells in a mixed live-dead population and also used as a counterstain in multicolor fluorescent assays.

Oxazole Gold, also known as SYBR® Gold, is the most sensitive fluorescent gel stain available for DNA and RNA.

Thiazole Green, which is structurally identical to SYBR® Green I Nucleic Acid Gel Stain, is one of the most sensitive stains available for detecting double-stranded DNA (dsDNA) in agarose, polyacrylamide gels and qPCR.

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

A two-color viability staining kit optimized specifically for gram-positive bacteria strains. Offers a simple 30-minute staining protocol, no wash required.

Highly-selective dead cell stains for bacteria cultures. The stains are suitable for both gram-positive and gram-negative strains.

DAPI is a popular blue fluorescent DNA dye. The dye binds to the minor groove of dsDNA with approximately 20-fold fluorescence enhancement.

Oxazole Red, also known as YO-PRO®-3, is a far-red fluorescent, cell-impermeant nucleic acid stain that can be used to stain dead or fixed cells.

Oxazole Red Homodimer, also known as YOYO®-3, is a far-red fluorescent, cell-impermeant nucleic acid stain that can be used to stain dead or fixed cells.

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

Oxazole Yellow Homodimer, also known as YOYO®-1, is a green-fluorescent, cell-impermeant nucleic acid stain that can be used to stain dead or fixed cells.

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.

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.
