This Super Fluor 680, SE is a reactive dye for the labeling of antibodies, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection.
PA Janelia Fluor 646, SE (PA-JF646-NHS), a photoactivatable fluorescent dye, is an NHS ester for coupling to primary amine groups. PA-JF646-NHS is 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 . PA-JF646-NHS is used for single molecule tracking and super resolution microscopy in live cells, specifically live cell sptPALM and fixed cell PALM. (λ Excitation/emission ~650/664 nm).
Janelia Fluor 669, SE (JF669, SE), a red fluorescent dye, can be directly reacted with the available thiol-containing HaloTag ligand under mild conditions (DIEA, DMF) to afford a JF669 HaloTag ligand in a single step (Ex = 669 nm; Em = 682 nm).
PA Janelia Fluor 549, SE (PA-JF549-NHS) is a bright photoactivatable fluorophore of JF549, SE (JF549, NHS). JF549, SE (JF549, NHS) is a fluorescent dye with the absorption maximum (λab (max)) of 549 nm and emission maximum (λem (max)) of 571 nm.
