Stat1 Double Nickase Plasmid (m): sc-423174-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Stat1 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
- Stat1 Double Nickase Plasmid (m) and Stat1 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Stat1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Stat1 Antibody (C-136): sc-464

Signal transducer and activator of transcription 1 (Stat1) is a central transcription factor in interferon-driven innate and adaptive immune signaling in mouse cells. Upon activation downstream of JAK kinases, STAT1 forms homo- or heterodimers and translocates to the nucleus to regulate interferon-stimulated genes involved in antiviral defense, antigen presentation, apoptosis, and growth control. Stat1 activity integrates cues from IFN-α/β and IFN-γ pathways and intersects with inflammatory signaling networks that shape macrophage activation and T cell responses. Dysregulated Stat1 signaling is widely studied in contexts of immune dysfunction and inflammation, and it also influences susceptibility to infection and tumor immune surveillance in experimental models.
Stat1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Stat1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Stat1. 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 Stat1 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 Stat1-disrupted clones.
