SIRT7 Double Nickase Plasmid (m): sc-431608-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- SIRT7 Double Nickase Plasmid (m) consists of a pair of plasmids each encoding a D10A mutated Cas9 nuclease and a target-specific 20 nt guide RNA (gRNA) designed to knockout gene expression with greater specificity than its CRISPR/Cas9 KO counterpart
- Paired gRNA sequences are offset by approximately 20 bp to allow for specific Cas9-mediated double nicking of the genomic DNA, which mimics a DSB
- One plasmid in the pair contains a puromycin-resistance gene for selection; the other plasmid in the pair contains a GFP marker to visually confirm transfection
- SIRT7 Double Nickase Plasmid (m) and SIRT7 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Sirt7. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: SIRT7 Antibody (C-3): sc-365344

Mouse Sirt7 encodes SIRT7, a nuclear NAD⁺-dependent deacylase enriched in the nucleolus that regulates ribosomal RNA transcription, chromatin organization, and genome stability. SIRT7 modulates transcriptional programs through deacetylation of histone and non-histone substrates and interfaces with ribosome biogenesis, DNA damage response, and metabolic stress signaling pathways. Altered SIRT7 activity has been linked to dysregulated proliferation, mitochondrial and metabolic remodeling, and age-associated cellular phenotypes in experimental models. These functions make Sirt7 a useful target for mechanistic studies of nucleolar homeostasis, epigenetic control of gene expression, and stress-adaptive transcriptional networks.
SIRT7 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Sirt7 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Sirt7. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt Sirt7 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of Sirt7-disrupted clones.
