Product Details

Biological Activity

OptoBI-1 is a photoswitchable TRPC3/6/7 agonist (EC50 for active cis-form ~0.1 μM at TRPC3). Switches conformation from trans to cis at 365 nm and cis to trans at 430 nm. Returns to trans conformation in the dark after ~ 50 minutes. No effect observed on TRPC4 or 5. Rapidly changes TRPC3 conductance and inhibits neuronal firing in cis-state.

Technical Data
