Tocris offers the following scientific literature in this area to showcase our products. We invite you to request* your copy today!
*Please note that Tocris will only send literature to established scientific business / institute addresses.
Produced by Tocris, the chemogenetics research bulletin provides an introduction to chemogenetic methods to manipulate neuronal activity. It outlines the development of RASSLs, DREADDs and PSAMs, and the use of chemogenetic compounds. DREADD ligands and PSEMs available from Tocris are highlighted.
GPCRs can interact with multiple distinct transducers or regulatory proteins and these can be preferentially engaged in an agonist-specific manner giving rise to biased agonism. This poster discusses cutting edge GPCR signaling pharmacology and highlights therapeutic applications of biased agonism.
