Human CRISPR Activation Library (SAM 2-plasmid system)
(Pooled Library #1000000078)

  • Purpose

    Version 2 of the human CRISPR/Cas9 SAM (Synergistic Activation Mediator) pooled library. This library uses an engineered protein complex for the transcriptional activation of endogenous genes.

    For SAM gain-of-function screening, this gRNA library has to be combined with one additional SAM construct, MS2-P65-HSF1 (Addgene plasmid #89308), which is provided with the library.

    Note: Libraries ordered prior to 4/3/2017 were shipped with Addgene plasmid #61426 rather than #89308

  • Vector Backbone

    lentiSAMv2 (Plasmid #75112) - this backbone contains dCas9-VP64-Blast and sgRNA(MS2)

Library Shipping

Each library is delivered in microcentrifuge tubes on blue ice. A tube's contents will not necessarily be frozen. For best results, minimize freeze/thaw cycles.

  • Volume
    ~20 µL
  • Concentration
    50 ng/µL

You will also receive a bacterial stab of the MS2-P65-HSF1 plasmid (Addgene #89308). Please do NOT order this plasmid in addition to this library.

Resource Information

Depositor Comments

The SAM library consists of three unique sgRNAs targeting the RefSeq coding isoforms in the proximal promoter (> 90% of sgRNAs are targeted to the first 200 bp upstream of the transcription start site of their target).

The lentiSAMv2 backbone contains Psi+, RRE, cPPT, U6, sgRNA (MS2), EFS, dCas9 (D10A/N863A), NLS, VP64, P2A, Blast, and WPRE.
