Pan-cancer CasRx lncRNA Albarossa Library
(Pooled Library #212966)

  • Purpose

    The human CasRx CRISPR lentiviral library encodes 75,725 gRNA arrays (two gRNAs per array) targeting 24,171 lncRNAs. lncRNAs are targeted by 2-7 arrays, depending on the length and other lncRNA characteristics. The library has been designed for its application across solid cancers. Target selection/prioritization for the library is based on lncRNA expression (across 839 solid cancer cell lines), evolutionary conservation, and tissue specificity, thereby reconciling high discovery power and pan-solid-cancer representation with scalable experimental throughput.

  • A CasRx plasmid is NOT included with this item and will have to be ordered separately. Can be used with plasmids expressing CasRx such as pTransposon.CAG.CasRX-P2A-Blast (#212965) or used with cell lines already expressing CasRx.

    50 ng/µL

Depositor Comments

The custom pipelines for gRNA arrays quantification from amplicon-seq data and the computational analysis of the CasRx lncRNAs screens are available at Github (Link opens in a new window).
