CRISPR genome editing enables precise, intentional, and permanent changes in the DNA of living organisms and cells. This editing technology relies on Cas enzymes and guide RNAs (gRNAs) and allows for genetic changes to be made at a targeted site.
Scientists select an appropriate Cas enzyme and design a gRNA targeting a genomic site. After synthesis, gRNA is combined with the Cas enzyme, forming a ribonucleoprotein (RNP). The RNP is delivered to cells by various means such as electroporation, and genome editing takes place inside cells. For a quantitative assessment after editing, DNA from edited cells can be sequenced by next generation sequencing (NGS).
For additional target sites or for targeting AT-rich regions, use the CRISPR-Cas12a system in electroporation experiments. Protospacer adjacent motif (PAM) = TTTV. The Alt-R Cas12a (Cpf1) Ultra also can recognize many TTTT PAM sites in addition to TTTV motifs, increasing target range for genome editing studies.
Select from our predesigned gRNAs targeting human, mouse, rat, zebrafish, or nematode genes. For other species, use our proprietary algorithms to design custom gRNAs. For protospacer designs of your own or from publications, use our design checker tool to assess targeting potential before ordering gRNAs that are synthesized using Alt-R gRNA modifications.
