About Janelia Fluor 646b, Maleimide

Janelia Fluor 646b, Maleimide has an excitation peak at 662 nm and an emission peak at 674 nm. Janelia Fluor 646b, Maleimide is a spontaneously blinking fluorescent dye, supplied with a maleimide reactive group for conjugation (thiol reactivity) for the labeling of protein. Suitable to characterize the physical properties of dense biomolecule condensates and complex macromolecular assemblies. Spontaneously Blinking Janelia Fluor® Dyes allow facile single-molecule localization microscopy (SMLM) in cells and dense biomolecular structures, without the need for photoactivation or redox buffers. These spontaneously blinking dyes harness Janelia Fluor® technology to delivery dyes that automatically cycle between 'off' and 'on' states with an ideal duty cycle for super resolution microscopy experiments. Derived from Janelia Fluor® 646, Maleimide.
