ENCODING OF DNA VECTOR IDENTITY VIA ITERATIVE HYBRIDIZATION DETECTION OF A BARCODE TRANSCRIPT

摘要

Embodiments disclosed herein are directed to a new genetic perturbation and screening method that combines advantages of pooled perturbation with imaging assays for complex phenotypes. Specifically, the method may be used to screen pooled genomic perturbations to identify phenotypes and to identify perturbed genes at the single-cell level using optical barcodes. A major advantage offered by this approach is the ability to screen for any cellular phenotype that can be identified by high-resolution microscopy—including live-cell phenotypes, protein localization, or highly multiplexed expression profile and mRNA localization by RNA-FISH—in conjunction with a large array of genetic perturbations applied as a pool in a single test volume.
