#U0600R Red GECO Ca2+ Assay Kit
$795.00 – $2,895.00
Red fluorescent calcium assay for detecting real-time calcium signaling on fluorescence plate readers and imaging systems. Standard stock comes with CMV promoter. Other promoters are available, please inquire!
The fluorescent, genetically-encoded Ca2+ indicator (GECO) was developed by Robert Campbell’s lab at University of Alberta. R-GECO can be paired with green fluorescent cADDis, cAMP sensor, or our Upward and Downward DAG sensors to simultaneously detect both Ca2+ and cyclic AMP or Ca2+ and diacylglycerol in living cells. The BacMam delivery system enables consistent and controllable expression in a wide variety of cell types including iPSC-derived cardiomyocytes and neurons. More details on this tool can be found on the Calcium Assays page.
Materials in the Kit:
• R-GECO Ca2+ Sensor BacMam
• Sodium Butyrate, 500 mM in H2O
• Z0200G M1 Muscarinic acetylcholine Receptor BacMam with nuclear green label
• Carbachol 25 mM in H2O
