Purpose
The Mouse Base Editing Sensor (MBES) and Human Base Editing Sensor (HBES) libraries are made up of sgRNAs that target frequently occurring cancer-associated mutations identified in the MSK IMPACT dataset that can be modeled with cytosine base editing. The ALL-PAM sensor (AP) library is made up of 10 human and mouse sgRNAs, where for each sgRNA the tethered target site has 1 of 64 possible 3-bp PAM sequences. Notably these "sensor libraries" also contain the cognate genomic target site within the same expression cassette for quantification of base editing efficiency.

Explore the library targets and browse guide RNAs by species, gene, target mutation, and/or base editor at the BE-SCAN web application (Link opens in a new window). The base editor sensor libraries were generated using the AMINEsearch pipeline available on GitHub (Link opens in a new window).
These pooled libraries were created by your colleagues. Please acknowledge the Principal Investigator, cite the article in which the plasmids were described, and include Addgene in the Materials and Methods of your future publications.
