Nuclease-independent applications of CRISPR provide equal targeting specificity but instead of cutting, CRISPRi allows for targeted interference of gene function by delivering transcriptional repressor domains to a specific target sequence using modified dCas9 + gRNA complexes. Gene knockdown is complementary to CRISPR-KO and CRISPRa (activation) and has distinct advantages over existing loss-of-function strategies like RNAi.…
Patient-derived organoids (PDOs) are novel in vitro 3D cell models that preserve original tissue physiology and molecular pathology.
The T7 Endonuclease Detection Assay is a well-known method for detecting genome editing events from CRISPR, Zinc-finger nuclease, and TALEN gene targeting. Originally identified from Escherichia coli bacteriophage, the T7 endonuclease can cleave mismatched heteroduplex DNA, Holliday junctions, branched DNA, and cruciform DNA.
All-in-one, ready-to-use Cas9 and guide RNA (gRNA) expression plasmids for use with monocots and dicots.
CRISPR/Cas9-mediated recombineering is the most powerful bacterial genome engineering method to date. In addition, Cas9-mediated recombineering overcomes the dependence on a second recombination step, avoids the creation of destabilizing scar sites, can be used in multiplexing, and is less time-consuming than previous protocols.
This Lentiviral Packaging Mix is an optimized formulation of two plasmids expressing the key HIV packaging genes and a heterologous viral envelope gene.
Universal negative control CRISPRs have been designed not to recognize any sequence in the human, mouse or rat genome.
