LANCE® Ultra Tyrosine (Tyr) Kinase ULight Substrates (acceptor dye conjugates) by Revvity

For kinase assays, ULight directly-labeled peptides simplify the assay format reducing the number of components from 3 to 2. PerkinElmer provides the kinase recognition sequence directly-labeled with our proprietary red-shifted dye. We have conducted extensive testing of the substrates performance with corresponding kinases. Refer to the Tyr substrate selection guide for assistance in choosing the best acceptor dye sequence and donor dye EU-conjugate for you kinase assay.
