Bassik Mouse CRISPR Knockout Library
(Pooled Libraries #1000000121, #1000000122, #1000000123, #1000000124, #1000000125, #1000000126, #1000000127, #1000000128, #1000000129, #1000000130)

  • Purpose

    This lentiviral genome-scale CRISPR library targets all ~23,000 protein-coding genes in the mouse genome. The library is divided into 10 sublibraries defined by biological categories, and each of these is then split randomly by gene into two half libraries (A and B).

    This library includes safe-targeting controls, gRNAs which target the genome but are not expected to disrupt gene function, in addition to nontargeting controls. The gRNAs vary in length from 17-20 bp, with the truncated gRNAs (17 or 18 bp) having less off-target activity.

  • Vector Backbone

    pMCB320 - does not express Cas9

  • A Cas9 plasmid is NOT included with this item and will have to be ordered separately. Can be used with plasmids expressing Cas9 such as lentiCas9-Blast (#52962) or otherwise used with cell lines already expressing Cas9.

  • If you would like to receive all ten sublibraries in a single order, please email [email protected] for pricing (if you use a distributor in your country, please contact your distributor directly for pricing).

Library Shipping

This library is delivered as suspended DNA in two microcentrifuge tubes on blue ice. Each tube contains one half sublibrary. The tubes' contents will not necessarily be frozen. For best results, minimize freeze-thaws.
