Guide-it Mutation Detection Kit

A faster and simpler method than the surveyor assay for identifying mutations such as insertions or deletions in mammalian cells

The Guide-it Mutation Detection Kit contains all the reagents needed for PCR-based identification of insertions or deletions generated in the genome of cells treated with engineered nucleases such as zinc-finger nucleases (ZFNs), transcription-activator-like effector nucleases (TALENs), or CRISPR/Cas9. The first step is the amplification of the putative target sequence directly from cells. This kit uses Terra PCR Direct Polymerase Mix and Buffer, so there is no need to extract genomic DNA from your cell population prior to amplification of your target sequence. The amplicon is then melted and hybridized to form the mismatched targets for cleavage by the Guide-it Resolvase. Agarose gel electrophoresis can be used to visualize the cleavage products.

The Guide-it Mutation Detection Kit contains all the reagents needed for PCR-based identification of insertions or deletions generated during cellular non-homologous end joining (NHEJ) repair. The first step is the amplification of the putative target sequence directly from cells. This kit uses Terra PCR Direct Polymerase Mix and Buffer, so there is no need to extract genomic DNA from your cell population prior to amplification of your target sequence. The amplicon is then melted and hybridized to form the mismatched targets for cleavage by the Guide-it Resolvase. Sufficient material is provided for 100 amplification and cleavage reactions.

Transfected cells were harvested 48 hr post-transfection and mixed with untransfected cells at varying ratios. An amplicon containing the targeted AAVS1 locus was generated using Terra Direct Polymerase Mix, and the PCR products were purified and cleaved using either Guide-it Resolvase or the Cel1 enzyme (Surveyor assay). Mutations were easily discernable when using the Guide-it kit. In contrast, the Surveyor Assay showed considerable smearing, making it difficult to determine cleavage efficiency and reducing the ability to detect low levels of mutation.

The cell population was assayed 6 days post-transfection for cleavage efficiency and loss of fluorescence. Panel B. Using the Guide-it Mutation Detection Kit, cleavage products were detected for both sgRNAs, indicating that both CRISPRs successfully disrupted the AcGFP1 locus. Panel C. The AcGFP1 disruptions were functionally relevant, as a subpopulation of non-fluorescent cells could be detected by FACS. Back 631448: Guide-it Mutation Detection Kit

The CRISPR/Cas9 system relies on a single guide RNA (sgRNA) directing the Cas9 endonuclease to induce a double strand break at a specific target sequence three base-pairs upstream of a PAM sequence in genomic DNA. This DNA cleavage can be repaired in one of two ways: 1) nonhomologous end joining, (NHEJ) resulting in gene knockout due to error-prone repair (orange), or 2) homology-directed repair (HDR), resulting in gene knockin due to the presence of a homologous repair template (purple).
