CRISPRi Library
(Pooled Library #62217)

  • Purpose

    Note: This library has been replaced by an updated version (see Depositor Comments below).

    Human genome-scale CRISPRi library for inhibition of gene transcription. Expresses a gRNA from the U6 promoter and a puromycin resistance cassette and BFP from the EF1Alpha promoter.

  • Vector Backbone

    pSICO derivative- does not express Cas9


Item Catalog # Description Quantity Price (USD)
Pooled Library 62217
  • CRISPRi pooled library

Available to Academic and Nonprofits Only
  • A Cas9 plasmid is NOT included with this item and will have to be ordered separately, or otherwise used with cell lines already expressing Cas9.

Library Details

  • Species
  • Genes targeted
  • gRNAs
  • Controls
  • Lentiviral Generation

Library Shipping

This 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
    50 ng/µL

Depositor Comments

Note: This item has been discontinued. The Weissman lab has released an updated version of the library here.

The library should be amplified before attempting to create virus. The use of high efficiency, electrocompetent cells is strongly advised (e.g. NEB DH5a cells, Invitrogen DH5a cells, or Lucigen Endura). Follow manufacturer's suggested protocol for transformation.

To ensure the maintenance of library diversity, calculate your transformation efficiency. 30x coverage of the library is recommended.

Plasmid pHR-SFFV-dCas9-BFP-KRAB (#46911) was used for stable expression of the dCas9-KRAB fusion protein for CRISPRi experiments in the associated publication. Plasmid pHR-SFFV-KRAB-dCas9-P2A-mCherry (#60954) is a non-inducible version of the KRAB-dCas9 construct described in Figure 5A of the paper.
