High throughput single-cell detection of multiplex CRISPR-edited gene modifications

Genome Biol. 2020 Oct 20;21(1):266. doi: 10.1186/s13059-020-02174-1.

Abstract

CRISPR-Cas9 gene editing has transformed our ability to rapidly interrogate the functional impact of somatic mutations in human cancers. Droplet-based technology enables the analysis of Cas9-introduced gene edits in thousands of single cells. Using this technology, we analyze Ba/F3 cells engineered to express single or multiplexed loss-of-function mutations recurrent in chronic lymphocytic leukemia. Our approach reliably quantifies mutational co-occurrences, zygosity status, and the occurrence of Cas9 edits at single-cell resolution.

Keywords: CRISPR-Cas9; Genetics; Genome editing; Loss-of-function; Mutation; Single cell; chronic lymphocytic leukemia.
