Nucleic Acid Binding Dyes
Propidium Iodide (PI)
40016, 40017, - 40048View allHide
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 (SYBR® Gold), 10,000X in DMSO
Oxazole Gold, also known as SYBR® Gold, is the most sensitive fluorescent gel stain available for DNA and RNA.
Thiazole Green (SYBR® Green I), 10,000X in DMSO
40086-0.5mL, - 40086-1mLView allHide
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.
GelRed® Nucleic Acid Gel Stain
41001, 41002, 41003, 41002-1, 41003-1, - 41003-TView allHide
Ultra sensitive and environmentally safe replacement for EtBr DNA/RNA gel stain.
NucSpot® 470 Nuclear Stain
40083-T, - 40083View allHide
Cell membrane-impermeant, nuclear-specific green counterstain. Suitable for fixed cells or staining dead cells in live cultures.
EverBrite™ Hardset Mounting Medium
23003, - 23004View allHide
A revolutionary antifade mounting medium optimally formulated for preserving fluorescence of our CF® dyes and other fluorochromes. EverBrite™ Hardset mounting medium hardens at room temperature completely in 24 hours.
MB-Maleimide
A commonly used redox indicator in nucleic acid research. MB-Maleimide can be used to label molecules containing free thiol groups.
MB-Azide
A commonly used redox indicator in nucleic acid research. MB-Azide can be used to label alkyne, BCN, or phosphine-containing molecules.
MB-TCO
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.
MB-Methyltetrazine
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.
MB-DBCO
A commonly used redox indicator in nucleic acid research. MB-dibenzocyclooctyne (DBCO) allows copper-free bioorthogonal conjugation to spontaneously label molecules containing azide groups.
DAPI
40011, 40043, - 40009View allHide
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 (YO-PRO®-3), 1 mM in DMSO
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 (YOYO®-3), 1 mM in DMSO
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 (POPO™-1), 1 mM in DMSO
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 (YOYO®-1), 1 mM in DMSO
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.
