Janelia Fluor 526®, SE
Biological Activity for Janelia Fluor 526®, SE
Janelia Fluor 526®, SE is a janelia Fluor 526® is a fluorogenic yellow fluorescent dye; supplied as an NHS ester for coupling to primary amine groups. NHS ester can be converted to relevant substrate for use in self-labeling tag systems, e.g. HaloTag® and SNAP-tag®. Suitable for confocal fluorescent imaging and super-resolution microscopy (SRM) techniques, such as dSTORM (live and fixed cells) and STED. Can be multiplexed for two color imaging with Janelia Fluor® 635 SE (Cat. No. 6419). Cell permeable. Excitation maximum = 526 nm; emission maximum = 550 nm; quantum yield = 0.87; Extinction coefficient = 118,000 M-1cm-1.
To measure the absorbance spectrum of this dye we recommend the following solvent: TFE plus 0.1% TFA.
We also offer Janelia Fluor® conjugated antibodies and custom conjugation services with our sister company Novus Biologicals.
