Janelia Fluor 585, se

Biological Activity

Janelia Fluor? 585, SE is an orange fluorogenic 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). Cell permeable. Excitation maximum = 585 nm; emission maximum = 609 nm; Quantum yield = 0.78; Max extinction coefficient = 156,000 M-1cm-1 (measured in Ethanol or TFE plus 0.1% TFA); Correction factor = 0.0990. Exhibits low non-specific background staining. Please see the protocol for further information on protein/antibody labeling and conjugation. To measure the absorbance spectrum of this dye we recommend the following solvent: trifluoroethanol plus 0.1% TFA. We also offer Janelia Fluor? conjugated antibodies and custom conjugation services with our sister company Novus Biologicals. HaloTag is a trademark of Promega Corporation, and SNAP-tag is a trademark of New England BioLabs, Inc.
