Abstract

Fluorescent protein-based Genetically Encoded Voltage Indicators (GEVI) offer a remarkable system for high-throughput screening of membrane potential phenotypes. The GEVI MARINA is a derivative from ArcLight, which conversely to ArcLight increases its fluorescence intensity alongside depolarization. Here we created knock-in reporter human iPS cell lines carrying the MARINA reporter using SpCas9 programmable nuclease and characterize a heterozygous clone.
