Glycogen synthase peptide (Sequence: PASVPPSPSLSRHSSPHQ(pS)ED) labeled with ULight™ dye. Synthetic peptide containing residues surrounding Ser641 and Ser657 of human Muscle Glycogen Synthase. This peptide is pre-phosphorylated on Ser657. Target phosphorylation site: Ser641. This peptide substrate can be phosphorylated by a variety of kinases including GSK3α and GSK3β.
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.
