Background:
Red 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). Also suitable for flow cytometry. Cell permeable. Excitation maximum = 635 nm; emission maximum = 652 nm; Quantum yield = 0.56; Max extinction coefficient = 167,000 M-1cm-1 (measured in Ethanol or TFE plus 0.1% TFA); Correction factor = 0.0524. Exhibits low nonspecific background staining. To measure the absorbance spectrum of this dye we recommend the following solvent: ethanol or 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.
