| Description | Janelia Fluor 585, SE (JF585, SE) is an orange fluorescent dye with an NHS ester that can conjugate with primary amine groups, making it immediately useful for structured illumination (SIM) and stimulated emission depletion (STED) imaging, and convertible to a photoactivatable derivative for single-molecule localization microscopy (SMLM) experiments. |
| In vitro | The chemical compound exhibits a maximum absorption wavelength (λabs) of 585 nm and a maximum emission wavelength (λem) of 609 nm[1]. The JF585-SNAP-tag ligand (24) serves effectively as a cellular label. Furthermore, the novel HaloTag ligands, developed from JF585 and JF635, display significant chromogenicity and fluorogenicity, essential for advanced imaging experiments[1]. |
