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.

The amine reactive succinimidyl ester of EB (ethidium bromide) can be conjugated to peptides, proteins, drugs, polymeric materials and biomolecules with primary amine groups.  The conjugates are expected to be essentially nonfluorescent until they are able to complex with nucleic acids, resulting in red fluorescence.

A red fluorescent dead cell stain for bacteria and mammalian cells that is brighter than Ethidium Homodimer I.

A red fluorescent dead cell stain for bacteria and mammalian cells

A patented green fluorescent nucleic acid dye with features that are ideal for applications such as qPCR, HRM®, LAMP, and digital PCR. Highly concentrated for customers with specialized applications requiring a concentrated dye solution.

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.

A commonly used redox indicator in nucleic acid research. MB-Azide can be used to label alkyne, BCN, or phosphine-containing molecules.

A commonly used redox indicator in nucleic acid research. MB-dibenzocyclooctyne (DBCO) allows copper-free bioorthogonal conjugation to spontaneously label molecules containing azide groups.

A commonly used redox indicator in nucleic acid research. MB-Maleimide can be used to label molecules containing free thiol groups.

A commonly used redox indicator in nucleic acid research. MB-methyltetrazine may be used to label TCO (trans-cyclooctene) tagged molecules via a copper-free reaction.

A commonly used redox indicator in nucleic acid research. MB-TCO (trans-cyclooctene) may be used to label tetrazine tagged molecules via a copper-free reaction.

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

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.
