The resultant DMR signal offers a novel and functional optical signature for studying GPCR signaling and screening GPCR drug compounds. The theoretical considerations and assay principles are first described. The unique optical signatures for over 20 endogenous Gq, Gs and Gi-coupled receptors in A431 human epidermoid carcinoma cells are presented. As exampled in studying the signaling pathways and network interactions of endogenous GPCRs, as well as screening GPCR ligands using both kinetic and endpoint measurements, Corning® Epic™ system is an easily scaleable biosensor HTS platform for Gq, Gs and GiGPCR drug discovery and deorphanization.
We utilized paired synthetic crRNAs coupled with our synthetic tracrRNA in cells transduced with lentiviral Cas9 to perform a functional knockout on hsa-miR-221. This three-part system (crRNA, tracrRNA and Cas9) has demonstrated efficient gene editing when used with only one guide RNA, but the goal was to use two crRNAs to remove the entire stem-loop.READ MORE
