Diabetes
Gain insight into diabetes disease mechanisms and GLP-1 receptor pharmacology with bright fluorescent biosensor assays.
Examine Biased agonism at the GLP-1 receptor in cell models and GPCR second messenger signaling in pancreatic islet cells.
GPCR Signaling in Diabetes
Monitor GPCR second messenger signaling kinetics with live-cell, fluorescent GPCR assays. Green and red fluorescent biosensor assays can be combined to detect simultaneous signaling in the same cells or wells. Co-transduce GPCRs like the GLP-1 receptor (#Z0600N) in cell models of diabetes. Monitor bright fluorescent assay signals on automated plate readers or imaging systems.
DAG Assay
PIP2 Assay
cADDis cAMP Assay
GECO Calcium Assay
Dose-dependent cAMP responses in HEK293 cells co-expressing GLP-1 receptor.
Expression in Pancreatic Islet Cells
Use assay-ready BacMam vectors to express fluorescent biosensors in pancreatic islets and image signaling kinetics. Target expression to specific cell sub-populations with custom promoters.
