生物活性 for JFX™ 554, Maleimide
Key Information: JFX™ 554, Maleimide is a yellow fluorescent deuterated Janelia Fluor® dye; supplied with a Maleimide reactive group for conjugation (thiol reactivity). Suitable for live cell imaging.
Application: Suitable for confocal microscopy, super-resolution microscopy (SRM) techniques including dSTORM (in both live and fixed cells) and STED. Cell permeable.
Properties and Photophysical Data: JFX™ 554, Maleimide shows enhanced brightness, photostability and chromostability. Maleimide can be converted to relevant substrate for use in self-labeling tag systems, e.g. HaloTag® and SNAP-tag®. Excitation and emission maxima (λ) are 554 nm and 576 nm, respectively; quantum yield = 0.8; extinction coefficient = 104,600 M-1cm-1; lactone-zwitterion equilibrium constant (KL-Z) = 4.97.
Please see the product protocol for further information and a guide to protein/antibody labeling.
We also offer Janelia Fluor® conjugated antibodies and custom conjugation services.
