Summary: A comparison of the ability of short hairpin RNA (shRNA) and CRISPR/Cas9 screens to identify essential genes.in the human chronic myelogenous leukemia cell line K562. It was found that the precision of the two libraries in detecting essential genes was similar and that combining data from both screens improved performance. Notably, results from the two screens showed little correlation when dealing with essential genes. shRNA screening picked up hits that CRISPR/Cas9 didn’t. Thus combining the results from the two methods could reveal information that neither could on its own. |
