DNA Binding Dyes
Biotium has a wide selection of DNA-binding dyes for various applications. These include common classical dyes as well as novel dyes developed by Biotium.
Nuclear staining of cells in fluorescence microscopy: Biotium has developed novel nuclear stains such as Ethidium Homodimer III (EthD-III), RedDot™ dyes, and NucSpot® dyes. Click here for a complete listing of nuclear stains for fluorescence microscopy.
DNA dyes for gel staining: Biotium is the inventor of the two safest and most sensitive nucleic acid gel stains, GelRed® and GelGreen®.

GelGreen® is a sensitive, non-mutagenic and environmentally safer green fluorescent DNA gel stain.
GelRed® Agarose LE
41029-5G, - 41029-50GView allHide
Ultrapure molecular biology grade agarose pre-coated with GelRed® Nucleic Acid Gel Stain for convenient and safer preparation of precast gels.
GelGreen® Agarose LE
41030-5G, - 41030-50GView allHide
Ultrapure molecular biology grade agarose pre-coated with GelGreen® Nucleic Acid Gel Stain for convenient and safer preparation of precast gels.
6X GelRed® Prestain Loading Buffer with Orange Tracking Dye
6X GelRed® Prestain Loading Buffer is a DNA gel loading buffer containing GelRed® for one-step fluorescent staining and gel loading of DNA.
PAGE GelRed® Nucleic Acid Gel Stain
41014, 41008-500uL, - 41008-TView allHide
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.
RedDot™2 Far-Red Nuclear Stain, 200X in DMSO
40061, 40061-1, - 40061-TView allHide
A far-red cell membrane-impermeant nuclear dye with greater nuclear specificity than Draq7™. Ideal for fixed cell nuclear counterstaining with minimal cytoplasmic RNA staining.
EvaGreen® Dye, 20X in Water
31000, - 31000-TView allHide
A patented green fluorescent nucleic acid dye with features that are ideal for applications such as qPCR, HRM®, LAMP, and digital PCR.
AO Succinimidyl Ester
The amine reactive succinimidyl ester of AO (acridine orange) can be conjugated to peptides, proteins, drugs, polymeric materials and biomolecules with primary amine groups. The conjugates with green fluoroscence are able to complex with nucleic acids, resulting in green fluorescence nucleic acid conjugate adduct.
DMAO, 2 mM in DMSO
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.
EB Succinimidyl Ester
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.
Ethidium Homodimer III (EthD-III)
A red fluorescent dead cell stain for bacteria and mammalian cells that is brighter than Ethidium Homodimer I.
Ethidium Homodimer III (EthD-III), 1 mM in DMSO
A red fluorescent dead cell stain for bacteria and mammalian cells
EvaGreen® Dye, 2000X in DMSO
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 Acid
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.
MB Succinimidyl Ester
The amine reactive succinimidyl ester of MB (methylene blue) 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.
