Green PIP2 Assay (D0400G)
Green fluorescence decreases as PIP2 is hydrolyzed to produce DAG and IP3, activated by GPCRs coupled to Gq. Standard stock comes with CMV promoter. Other promoters are available, please inquire!
This sensor has now been packaged in our Big Sky BacMam vector, yielding greatly improved expression in cell types including HEK and CHO cells. The new product number is #D0450G, but #D0400G, is still available to purchase. Please reach out for a quote.
