Protein chip-based GLP-1 receptor assay system

Protein chip-based GLP-1 receptor assay system Abstract We investigated GLP-1 Receptor (GLP-1R) assay system on the basis of receptor-ligand interaction using ProteoChip. GLP-1R was immobilized on the surface of the ProteoChip and then GLP-1 peptide labeled with a Cy5-fluorescent dye was interacted with the GLP-1R array on the chip in a dose-dependent manner. Exendin-4 was tested for targeting GLP-1R to demonstrate the chip-based GLP-1R assay system. Chemical compound 6 and 45 were screened as novel agonists of GLP-1R using the GLP-1R assay system. The compound significantly inhibited GLP-1 binding to GLP-1R in a dose-dependent manner. The protein chip-based GLP-1R assay system will serve as a useful tool for screening of novel GLP-1R agonists. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png BioChip Journal Springer Journals

Abstract

Abstract We investigated GLP-1 Receptor (GLP-1R) assay system on the basis of receptor-ligand interaction using ProteoChip. GLP-1R was immobilized on the surface of the ProteoChip and then GLP-1 peptide labeled with a Cy5-fluorescent dye was interacted with the GLP-1R array on the chip in a dose-dependent manner. Exendin-4 was tested for targeting GLP-1R to demonstrate the chip-based GLP-1R assay system. Chemical compound 6 and 45 were screened as novel agonists of GLP-1R using the GLP-1R assay system. The compound significantly inhibited GLP-1 binding to GLP-1R in a dose-dependent manner. The protein chip-based GLP-1R assay system will serve as a useful tool for screening of novel GLP-1R agonists.
