About Janelia Fluor 630b, Maleimide

Janelia Fluor 630b, Maleimide has an excitation peak at 651 nm and an emission peak at 666 nm. Janelia Fluor 630b, Maleimide is a spontaneously blinking fluorescent dye, supplied with a maleimide reactive group for conjugation (thiol reactivity). 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 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.
