The Edit-R predesigned guide RNA guarantee
We guarantee that EVERY predesigned guide RNA will provide successful editing at the target site when delivered as described in the Edit-R Technical Manuals.
The Edit-R guide RNA guarantee is valid when used with any wild type S. pyogenes Cas9 nuclease, including mRNA, expression plasmid, protein, or stable Cas9 expression, and Edit-R crRNAs must be used with Edit-R tracrRNA for the guarantee to apply.
Analysis of editing of the treated cell population must be shown using a T7EI or Surveyor mismatch detection assay. If successful editing is not observed for a predesigned Edit-R guide RNA while an appropriate side-by-side Edit-R positive control is successful, a one-time replacement of a different predesigned Edit-R guide RNA of the same format and quantity will be provided at no cost.
A replacement will only be approved upon discussion with our Technical Support team.
Successful editing at the DNA level does not always lead to functional gene knockout; it is recommended to test multiple guide RNAs to determine the most effective guide RNA for knockout of your target gene.
This guarantee does not extend to any accompanying experimental costs, does not apply to guide RNAs ordered via the CRISPR Design Tool, and will not be extended to the replacement guide RNA.

Edit-R All-in-one lentiviral system percent editing (TIDE)
Jurkat or K562 cells were transduced at a MOI of 0.3 using Edit-R All-in-one EGFP Lentiviral sgRNA vectors targeting either the CD3 or CD28 genes. All-in-one lentiviral particles express Cas9 nuclease constitutively under the hEF1α or mCMV promoters. Lentiviral particles expressing Non-targeting control (NTC) guides were used as negative controls. After lentiviral transduction and expansion, cells were analyzed as unsorted population (pool) or were subjected to cell sorting to enrich for the brightest (top) or dimmest (dim) EGFP expressing cell populations. The pool, top, and dim populations of cells were then subjected to TIDE analysis to assess gene editing frequency.
Comparison of Edit-R two-vector and All-in-one systems

For the two-vector system, cells were previously transduced with a constitutive hEF1α- or mCMV-Cas9 expression lentiviral particles at an MOI of 0.3, and selected with 10 µg/mL blasticidin for 10 days, followed by transduction with non-targeting control (NTC), DNMT3B- or PPIB-sgRNA lentiviral particles at an MOI of 0.3. For the All-in-one system, wild-type cells were transduced with the All-in-one were selected with 2 µg/mL puromycin for 3 days. For the All-in-one system, wild-type cells were transduced with the NTC, DNMT3B or PPIB All-in-one lentiviral particles that also express a constitutive hEF1α- or mCMV-Cas9 nuclease, and the PuroR gene at an MOI of 0.3. All transduced cells were selected with 2 µg/mL puromycin for 3 days. The cells were then lysed and analyzed for indels using a DNA mismatch detection assay with T7EI.
Schematic diagram of the Edit-R All-in-one lentiviral sgRNA vector
In the Edit-R All-in-one lentiviral sgRNA vector backbone, the gene-specific guide RNA is expressed under the control of a human U6 promoter, while expression of the Cas9 and puromycin resistance marker (PuroR) or EGFP marker is driven from either the human EF1α or the mouse CMV promoter. The plasmid contains the AmpR resistance marker for growth and selection in E. coli.
