Biological Activity
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.Key Information: Janelia Fluor® 635b, 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.
Application: suitable for super resolution microscopy (SRM) including single-molecule localization microscopy (SMLM).
Properties and Photophysical Data: derived from Janelia Fluor® 635, Maleimide (Cat. No. 8027). Excitation and emission maxima (λ) are 651 nM and 667 nM, respectively.
