LANCE Ultra TR-FRET technology provides a two-component kinase assay that combines direct labeling of the kinase substrate with ULight™, an innovative emission dye for optimum binding efficiency, reducing steps and assay prep time. Validated for over 310 kinases, we provide data transparency by supplying:
For ULight substrates:
In LANCE Ultra kinase assays, the binding of a Eu-labeled anti-phosphosubstrate antibody to the phosphorylated ULight-labeled substrate brings donor and acceptor molecules into close proximity. After irradiation of the kinase reaction at 320 or 340 nm, the energy from the Eu donor is transferred to the ULight acceptor dye, which in turn generates light at 665 nm. The intensity of the light emission is proportional to the level of ULight-substrate phosphorylation.

LANCE® Ultra is a high through putscreening (HTS) technology platform optimized for homogeneous time-resolved fluorescence resonance energy transfer (TRFRET) kinase assays. The LANCEUltra donor dye is a Europium(Eu) chelate, and the acceptor dye is a proprietary small-molecular weight molecule called ULight™, a fluorescent dye with a red-shifted light emission.
LANCE® Ultra TR-FRET reagents comprise the widest portfolio of validated kinase assay offerings available for rapid, sensitive ,and robust screening of purified kinase targets in a biochemical format.
LANCE Ultra time-resolved fluorescence resonance energy transfer (TR-FRET) assays use a proprietary europium chelate donor dye with ULight, an innovative small molecular weight acceptor dye with a red-shifted fluorescent emission.
