Sanger CRISPR QuickPick™ Knockout Clones

  • MilliporeSigma and The Wellcome Trust Sanger Institute have partnered to create the world’s first whole genome arrayed CRISPR libraries. Together, the combined libraries contain over 74,000 individual CRISPR clones designed to maximize knockout of nearly every protein-coding gene in the human and mouse genomes. These ready-to-use constructs are now available to the global research community as individual clones, gene panels, and whole genome libraries.
  • Use the Ordering icon to the right to order human or mouse Sanger CRISPR clones in any one of three formats to knockout your gene of interest.
    Use the links below for specific information on each format:
    Bacterial glycerol stocks
    Transfection-grade plasmid DNA
    Lentiviral transduction particles

Sigma CRISPR Positive Controls

Recommended Uses: Validate the efficiency of your genome editing experiment or screen

  • Verify the success of your genome editing experiments with validated guide RNAs against the human EMX1 gene
  • Positive controls are available for both the wild type and nickase CRISPR systems
  • Wild type Cas9 or Cas9-D10A nicking enzyme is provided with the purchase of the corresponding control

Sigma CRISPR Universal Negative Controls

Recommended Uses: Confirm the veracity of your genome editing experiment or screen

  • Sigma’s Universal Negative Controls express a guide RNA that has been bioinformatically designed not to target any sequence in the human, mouse, or rat genomes.
  • Allows for the expression of Cas9 and GFP without targeting a DNA locus.
  • Universal Negative Controls are provided in Sigma’s all-in-one CRISPR vector expressing both Cas9 and a non-targeting guide RNA.
  • For most CRISPR experiments we recommend Universal Negative Control 1; Universal Negative Control 2 and 3 can be used as additional controls or as alternatives to Universal Negative Control 1.
  • Ready-to-ship in 2 business days.
