Live Cell Ca2+ Assay Kit-GECO
Real time kinetic calcium sensor for fluorescent plate readers and imaging sytems Order GECO Calcium AssaysThe GECO assays (R-GECO, G-GECO) are fluorescent calcium assays for real time kinetic readouts. This genetically encoded fluorescent sensor is available in both red or green versions, can be expressed in a variety of cell types for plate reader or imaging applications. Developed by Robert Campbell’s lab at University of Alberta, Montana Molecular packages these calcium sensors in viral vectors for robust expression in your favorite cells.
Bright Red and Green Fluorescent Calcium Sensors
- Genetically encoded for low toxicity
- Real-time kinetic readout
- Robust expression in variety of cell types
Multiplex Ca2+ Assay
Easily combine red or green GECO sensors with other GPCR sensors to measure multiple pathways simultaneously
GECO Assay Performance
Off the shelf kits include the GECO sensor in BacMam, a BSL-1 viral vector for efficientl delivery to most cell types. Purified BacMam, AAV, Lenti vectors by request.

“Assay is working beautifully with cardiomyocytes, showing a strong and immediate response.”
Expression in human islets is pretty superb, after 18 hours of incubation. An excellent probe!
