DNA Repair CRISPRi Libraries
(Pooled Libraries #177663, #177664, #177670)

  • Purpose

    These CRISPR-interference (CRISPRi) libraries contain sgRNAs targeting genes encoding factors involved in DNA repair and associated processes. These libraries can be used in Repair-seq experiments for mapping DNA repair pathways and identifying strategies to optimize genome editing. The backbone of #177663 and #177664 includes a Cas9 or Cas12a targeted site, while #177670 includes a prime editing targeted site.

    To perform Repair-seq experiments, transduce the CRISPRi library into cells expressing dCas-KRAB to deplete the target genes, then electroporate with ribonucleoprotein, plasmid, or mRNA of Cas9, Cas12, or prime editor with gRNA targeting the editing site on the library backbone.

  • Vector Backbone

    #177663 and #177664: pAX198 - does not express Cas9

    #177670: pPC1000 - does not express Cas9

  • A Cas9 plasmid is NOT included with this item and will have to be ordered separately. Can be used in conjunction with pHR-SFFV-dCas9-BFP-KRAB (Addgene #46911) or other plasmid(s) or cell lines expressing dCas9-KRAB.

Library Shipping

Each library is delivered as suspended DNA in a microcentrifuge tube on blue ice. The tube's contents will not necessarily be frozen. For best results, minimize freeze-thaws.

  • Volume
    ∼20 µL
  • Concentration
    10 ng/µL

Depositor Comments

More information, including interactive exploration of raw data, is available in the Repair-seq data browser (Link opens in a new window). Analysis scripts are available at GitHub (Link opens in a new window).

It is also recommended to PCR and sequence the initial library upon receipt. Note that we introduced the skewness in the library with 336 sgRNAs intentionally, to compensate for the loss of some toxic guides.
