CAT-2 Double Nickase Plasmid (h): sc-407551-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- CAT-2 Double Nickase Plasmid (h) 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
- CAT-2 Double Nickase Plasmid (h) and CAT-2 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting SLC7A2. One or both designs may be available

SLC7A2 encodes the cationic amino acid transporter CAT-2, a plasma membrane carrier that mediates sodium-independent uptake of L-arginine, L-lysine, and L-ornithine. By controlling intracellular arginine availability, CAT-2 influences nitric oxide synthase output, polyamine biosynthesis, and broader nitrogen and amino acid metabolism programs that shape cellular activation and stress responses. SLC7A2 activity is frequently studied in immune and inflammatory signaling contexts, where substrate flux can modulate redox balance and cytokine-driven phenotypes. Altered regulation of arginine transport pathways has been associated with cardiometabolic and inflammatory disease biology, making CAT-2 a useful target for mechanistic studies of arginine-dependent signaling networks.
CAT-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SLC7A2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SLC7A2. 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 SLC7A2 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 SLC7A2-disrupted clones.
