XIAP E3 Ligase TR-FRET Kit

Product description: South Bay Bio’s XIAP E3 Ligase TR-FRET Kit provides a fast and sensitive method monitoring ubiquitin conjugation onto XIAP in solution, resulting from an enzymatic ubiquitin cascade without the need of running and staining an SDS gel. The kit enables continuous TR-FRET detection of ubiquitin chain formation onto XIAP in a real-time detection setup, or in an end-point configuration if desired. TR-FRET uses the extended fluorescence emission decay lifetimes typical of rare-earth lanthanides to impart a short time-delay between FRET donor excitation and emission. This delay provides a means to separate “true” signal from short-lived background fluorescence, and reduce interference from compound fluorescence and other assay artifacts.
