Product Details

Biological Activity

Hoechst Janelia Fluor® 526 is a fluorogenic, green-emitting DNA probe. Preferentially stains and binds minor groove of AT-rich regions. When bound to A-T DNA, Hoechst Janelia Fluor® 526 exhibits a quantum yield (QY) of 0.126; when bound to G-C DNA Hoechst Janelia Fluor® 526 exhibits a quantum yield = 0.04.

Fluorogenic: fluoresces only once bound to DNA, enabling hassle-free no-wash experiments. Hoechst Janelia Fluor® 526 is suitable for multicolor microscopy experiments and for use in live cell imaging.

Excitation maximum = 531 nm; emission maximum = 549 nm.

To measure the absorbance spectrum of Hoechst Janelia Fluor® 526 we recommend the following solvent: TFE plus 0.1% TFA.
