Abstract

Pooled short-hairpin RNA (shRNA) library screening is a powerful tool for identifying a set of genes in biological pathways that require stable expression to produce a desired phenotype. Massive parallel sequencing of half-hairpins has proven highly variable and has not given satisfactory results concerning the relative abundance of different shRNAs before and after selection. Here, the authors describe a method for quantitative comparison of half-hairpins from pooled shRNAs in the mir30-based pGIPZ vector that is analyzed by massive parallel sequencing. Introducing a multiplexing code and refining the sample preparation scheme resulted in the predicted ability to detect twofold enrichments. These improvements should permit half-hairpin sequencing to analyze either dropout screens or selective pooled shRNA screens of limited stringency to analyze phenotypes not accessible in transient experiments.
