Edit-R Lentiviral sgRNA Non-targeting Controls

Lentiviral sgRNA constructs bioinformatically designed and validated to not target any gene in human, mouse or rat genomes.

Negative control sgRNAs to establish experimental baselines and to distinguish sequence-specific biological effects from non-specific effects. Available as high-titer purified lentiviral particles and glycerol stock formats.
CRISPR-Cas9 gene editing experiments require the use of negative control samples in order to accurately distinguish biological effects of sgRNA-induced editing of targeted genomic DNA from non-specific effects. Edit-R Lentiviral sgRNA Non-targeting Controls incorporate guide sequences that are bioinformatically designed and confirmed not to be homologous to any genes in the human, mouse and rat genomes.

Ten different negative control CRISPR RNA sequences are designed and provided as glycerol stocks and as 50 µL* (2 x 25 µL) purified, concentrated lentiviral particles. Due to the biological variability inherent in different cells, time points, assays and conditions, we recommend testing at least two non-targeting sgRNAs to identify the best negative control for establishing an effective baseline for your particular experiment. Edit-R Lentiviral sgRNA Non-targeting Controls are:

  • CRISPR guide RNA sequences cloned into the same optimized lentviral expression backbone as Edit-R gene targeing sgRNAs;
  • available as glycerol stocks and as purified, concentrated lentiviral particles which avoids toxicity due to cellular debris and nucleases resulting from the packaging reaction and present in supernatants;
  • designed and checked using an optimized alignment program for thorough specificity analysis of CRISPR guide RNA sequences, including detection of gapped alignments, which other alignment tools miss; and
  • verified bioinformatically to not be homologous to any genes in the human, mouse and rat genomes.

Schematic maps and table of vector elements of the Edit-R Lentiviral Cas9 Nuclease and sgRNA vectors.The Edit-R Lentiviral CRISPR-Cas9 platform is a two-vector system that utilizes a lentiviral vector with multiple Pol II promoter options for maximal Cas9 expression and a gene-specific vector for sgRNA expression designed to the target site of interest.

In the Edit-R Lentiviral sgRNA vector backbone, the gene-specific crRNA and the tracrRNA are expressed under the control of a human U6 promoter, while expression of the puromycin resistance marker (PuroR) is driven from the mouse CMV promoter and allows for rapid selection of cells with integrated sgRNA. The plasmid contains the AmpR resistance marker for growth and selection in E. coli.
