说明： Blinking fluorescent dye (Reactive group: NHS ester). Application: super resolution microscopy (SRM) including SMLM
化学名： 2,5-Dioxopyrrolidin-1-yl 3,7-bis(3-fluoroazetidin-1-yl)-5,5-dimethyl-3'H,5H-spiro[dibenzo[b,e]siline-10,1'-isobenzofuran]-6'-carboxylate
纯度： ≥90% (HPLC)
生物活性 for Janelia Fluor® 635b, NHS ester
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, NHS ester is a spontaneously blinking fluorescent dye, supplied with an NHS ester reactive group for the labeling of primary amines. Suitable for DNA labelling using amine-terminated oligonucleotides. Also used to label oligonucleotides for super-resolution assays of transposase-accessible chromatin (ATAC-SMLM).
Application: suitable for super resolution microscopy (SRM) including single-molecule localization microscopy (SMLM).
Properties and Photophysical Data: derived from Janelia Fluor® 635, SE (Cat. No. 6419). Excitation and emission maxima (λ) are 654 nM and 671 nM, respectively.
