Loss-of-function screening by CRISPR/Cas9 gene knockout with pooled, lentiviral
guide libraries is a widely applicable method for systematic identification of
genes contributing to diverse cellular phenotypes. Here, Random Sequence Labels
(RSLs) are incorporated into the guide library, which act as unique molecular
identifiers (UMIs) to allow massively parallel lineage tracing and lineage
dropout screening. RSLs greatly improve the reproducibility of results by
increasing both the precision and the accuracy of screens. They reduce the number
of cells needed to reach a set statistical power, or allow a more robust screen
using the same number of cells.
