Red Down DAG Assay Big Sky (D0350R)
Price range: $895.00 through $1,795.00
Monitor Gq-mediated changes in diacylglycerol on fluorescence imaging systems with the red fluorescent downward DAG assay. Standard stock comes with CMV promoter. Other promoters are available, please inquire!
This is an update to product #D0300R, the difference being that the DAG biosensor is packaged in Montana Molecular's Big Sky BacMam vector.
Measure diacylglycerol signaling in real time, in the living cells of your choice. This red fluorescent sensor decreases in fluorescence in response to increases in intracellular DAG. Our DAG Assay is genetically-encoded and packaged in a BacMam viral vector for easy transduction into a wide variety of cell types, including primary and iPSC-derived cell lines. The red fluorescent downward DAG assay starts bright and decreases in fluorescence in response to increasing DAG. Compatible with use on standard fluorescence microscopes and automated plate readers. Find additional details on the DAG Assays page.
Materials in the Kit:
• Red Down DAG Sensor BacMam
• Sodium Butyrate, 500 mM in H2O
• Human M1 muscarinic acetylcholine receptor BacMam with nuclear green label
• Carbachol 25 mM in H2O
