Description

Red photoactivatable dye (Reactive group: NHS ester). Application: super resolution microscopy (SRM), single molecule tracking and live cell imaging

Key information: PA Janelia Fluor™ 646, SE is a photoactivatable fluorescent dye; supplied with an NHS ester reactive group for the labeling of primary amines. Suitable for live and fixed cell imaging. Application: Suitable for single molecule tracking and super resolution microscopy in live cells, specifically sptPALM (live cells) and PALM (fixed cells) techniques. Properties and Photophysical Data: Non-fluorescent until activated at 365 nm. NHS ester can be converted to relevant substrate for use in self-labeling tag systems, e.g. HaloTag™ and SNAP-tag™. Can be multiplexed with PA Janelia Fluor™ 549, SE (Cat. No. 6149) to perform two-color sptPALM in live cells with activation at 405nm. Upon protein conjugation the efficiencies of photoconversion improve substantially. Low background staining. Excitation and emission maxima (λ) are 649 - 651 nm and 663 - 665 nm, respectively. Please see the protocol for further information on protein/antibody labeling and conjugation. HaloTag is a trademark of Promega Corporation, and SNAP-tag is a trademark of New England BioLabs, Inc.
