Supplementary Figure 4: Reporter screen of eight dCas9 tripartite repressors.
From: An enhanced CRISPR repressor for targeted mammalian gene regulation

A series of rationally designed tripartite repressors were generated based on the top-performing bipartite repression domains. Each repressor was tested using the same fluorescent reporter assay as in Supplementary Figure 1. n = 2 biologically independent samples (cell cultures).
