生物活性

Janelia Fluor® 646, Maleimide (JF646, Maleimide) is a red fluorescent dye that contains a maleimide group. JF646, Maleimide can be used in cellular imaging[1][2]. Janelia Fluor® products are licensed under U.S. Pat. Nos. 9,933,417, 10,018,624 and 10,161,932 and other patents from Howard Hughes Medical Institute.

体外研究
(In Vitro)

λmax (nm)=646; λem (nm)=664[1].
JF646 can serve as a ligand for self-labeling tag (such as HaloTag)[1].
JF646, Maleimide is modified by JF646. JF646, a red fluorescent dye, is photostable, membrane-permeable, has a high extinction coefficient[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
