Fatso Double Nickase Plasmid (m): sc-424024-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Fatso 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
- Fatso Double Nickase Plasmid (m) and Fatso Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Fto. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Fatso Antibody (C-3): sc-271713

Mouse Fto encodes the Fatso protein, an Fe(II)/2-oxoglutarate–dependent dioxygenase that functions as an RNA demethylase with preference for N6-methyladenosine (m6A) and related methylated adenosines. By modulating RNA methylation status, Fatso influences mRNA splicing, stability, translation, and decay, thereby shaping gene expression programs controlling energy balance and cell-state transitions. Fto activity integrates with nutrient-sensing and metabolic signaling networks, including pathways linked to adipogenesis and mitochondrial function. Dysregulated Fto expression or function has been associated with obesity-related traits and metabolic phenotypes, making it a widely used target in studies of epitranscriptomic regulation and metabolism-driven disease mechanisms.
Fatso Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Fto locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Fto. 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 Fto 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 Fto-disrupted clones.
