- Molecular Weight:568.50
IUPAC Name: 4-carboxy-3-(3,6-di(azetidin-1-yl)xanthylium-9-yl)benzoate compound with 2,2,2-trifluoroacetic acid (1:1)
InChIKey: GFUAWSMWTYTASE-UHFFFAOYSA-N
SMILES: O=C(C1=CC=C(C(O)=O)C(C2=C3C=CC(N4CCC4)=CC3=[O+]C5=C2C=CC(N6CCC6)=C5)=C1)[O-].O=C(O)C(F)(F)F
Biological Activity: Janelia Fluor 549 TFA (JF549 TFA) is a fluorescent dye with the absorption maximum (λab (max)) of 549 nm and emission maximum (λem (max)) of 571 nm[1]. Janelia Fluor fluorescent dyes can be chemically conjugated to the specific HaloTag substrate (a chloroalkane ligand) to form a fluorescent ligand, rather than binding directly to the HaloTag protein itself. 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.
