LUXendin762 GLP1 receptor (GLP1R) fluorescent antagonist (762/784) (CELT-113)

Our GLP1R fluorescent antagonist shows high affinity for GLP1 receptor (pIC50 = 7.0 for GLP1R) modulating the receptor by orthosteric antagonism. The efficacy and potency of LUXendin762 (CELT-113) as a GLP1R ligand was confirmed by a GLP-1 stimulated cAMP levels in SNAP-GLP1R:HEK293 cells. LUXendin762 (CELT-113) has been used in a variety of imaging applications, including widefield imaging in live and fixed mammalian cells and tissue. LUXendin762 is also compatible with non-invasive fluorescence preclinical imaging.
