Bradley Human CRISPR Poison Exon Knockout Library
(Pooled Library #138084)

  • Purpose

    The human pgPoison library targets 3` splice sites with paired gRNAs (pgRNAs), inducing skipping of "poison" cassette exons and corresponding upstream constitutive exons.

    This allows direct comparison between loss of a constitutive coding exon (knockout) with loss of a poison exon.

  • Vector Backbone

    lentiGuide-Puro - 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 lentiCas9-Blast (Addgene #52962), Lenti-iCas9-neo (Addgene #85400), or any other plasmid(s) or cell lines expressing Cas9.
