Europium W1024 ITC

Europium W1024 ITC is a lanthanide fluorophore with a reactive isothiocyanate group for labeling amines, featuring a long lifetime and large Stokes shift (Ex/Em 340/613 nm) . Its stability makes it ideal as a TR-FRET donor for in vitro assays, such as kinase activity and protein-protein interaction studies, minimizing background autofluorescence.
