LUXendin645 GLP1 receptor (GLP1R) fluorescent antagonist (645/664) (CELT-112)

Our GLP1R fluorescent antagonist shows high affinity for GLP1 receptor (pEC50 = 7.5 for GLP1R) modulating the receptor by orthosteric antagonism. The efficacy and potency of LUXendin645 (CELT-112) as a GLP1R ligand was confirmed by inhibition of GLP-1-stimulated cAMP levels in SNAP-GLP1R:HEK293 cells. LUXendin645 (CELT-112) has been used in a variety of imaging applications, including widefield/confocal/2-photon microscopy in live and fixed mammalian cells and tissue. Using TR-FRET, LUXendin645 was used in GLP1R competitive binding experiments and in GLP1R trafficking and recycling studies.
