| 产品描述 | Janelia Fluor 669, SE (JF669, SE), a red fluorescent dye, can be directly reacted with the available thiol-containing HaloTag ligand under mild conditions (DIEA, DMF) to afford a JF669 HaloTag ligand in a single step (Ex = 669 nm; Em = 682 nm). |
| 体外活性 | JF669 undergoes rapid conversion to thioether product (<5 min to completion) in organic solvents, where the dye predominantly adopts the closed form[1]. JF669 displays comparatively excellent photostability, retaining 97% fluorescence after the same number of cycles[1]. |
