| Application: | Functional Genomics/Transgenic Applications • Creation of gene knockouts in transgenic applications • Creation of knock-in animals with promoters, fusion tags or reporters integrated into endogenous genes |
| Biochem/physiol Actions: | CRISPR/Cas systems are employed by bacteria and archaea as a defense against invading viruses and plasmids. Recently, the type II CRISPR/Cas system from the bacterium Streptococcus pyogenes has been engineered to function in eukaryotic systems using two molecular components: a single Cas9 protein and a non-coding guide RNA (gRNA). The Cas9 endonuclease can be programmed with a single gRNA, directing a DNA double-strand break (DSB) at a desired genomic location. Similar to DSBs induced by zinc finger nucleases (ZFNs), the cell then activates endogenous DNA repair processes, either non-homologous end joining (NHEJ) or homology-directed repair (HDR), to heal the targeted DSB. |
| Features and Benefits: | RNA ready to use in transgenic applications. Must be used in conjunction with a purified guideRNA sequence to mediate a site specific double strand break in the DNA. |
| General description: | Cas9 mRNA generated through in-vitro transcription which has been capped and polyA-tailed. This mRNA should be used in conjunction with purified guideRNA. The use of RNA vs. plasmid constructs avoids complications with promoter-embryo compatibility as well as the possibility of random integration of nuclease and gRNA-expressing plasmids into the host animal genome. |

| Other Notes: | 1 vial containing 25ug of Cas9 mRNA. Please note, product does not contain guideRNA sequence. This must be purchased separately through the Custom CRISPR product tab. |
| Other Notes: | Must be used in conjunction with the RNA format of a guideRNA sequence in order to mediate a double strand break in the DNA. |
| Other Notes: | Typical microinjection concentrations used in the literature are in the ranges of 20-200 ng/ul for Cas9 mRNA and 10-50 ng/ul for gRNA. |
| Other Notes: | While Sigma CRISPR RNA was not developed for robust application to cell culture, we have seen some success in detecting CEL-I activity using RNA-only formats for both CRISPR nucleases and paired nickases. RNA-only delivery formats may be favorable for cell types which are sensitive to double stranded DNA such a dendritic cells or when promoter-cell incompatibilities exist. |
| Physical form: | Sigma Cas9 mRNA is supplied at a concentration of 500 ng/ul (50 ul Cas9 mRNA, capped and polyA-tailed) |
| Preparation Note: | While Sigma implements the same high quality RNA synthesis procedures that have been successful in many mRNA-based ZFN transgenic projects, we highly recommend centrifuging your final, concentration-adjusted CRISPR RNA samples immediately prior to microinjection to ensure all particulate material has been removed which may result in clogging of microinjection needles. |
