FAT1 Double Nickase Plasmid (m): sc-420291-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- FAT1 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
- FAT1 Double Nickase Plasmid (m) and FAT1 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Fat1. One or both designs may be available

Mouse Fat1 encodes FAT1, an atypical cadherin that regulates cell–cell adhesion, polarity, and directional migration through coordination of actin cytoskeletal dynamics and Hippo signaling components. FAT1 contributes to planar cell polarity and tissue morphogenesis by influencing junctional organization and membrane-associated signaling cues that shape epithelial architecture. Disruption of FAT1-dependent adhesion and polarity programs has been linked to developmental abnormalities and altered growth control in disease-relevant contexts, making it a useful node for studying how mechanical and signaling networks integrate to govern tissue integrity. In mouse models and cell systems, FAT1 provides a tractable entry point to investigate pathways connecting junctional cadherins, cytoskeletal remodeling, and contact-dependent regulation of proliferation.
FAT1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Fat1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Fat1. 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 Fat1 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 Fat1-disrupted clones.
