ARG1/Arignase 1 Double Nickase Plasmid (m): sc-419192-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- ARG1/Arignase 1 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
- ARG1/Arignase 1 Double Nickase Plasmid (m) and ARG1/Arignase 1 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Arg1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: ARG1/Arginase 1 Antibody (E-2): sc-271430

Mouse Arg1 encodes arginase 1 (ARG1), a cytosolic metalloenzyme that hydrolyzes L-arginine to L-ornithine and urea as a core step of the urea cycle and nitrogen disposal. By modulating intracellular arginine availability, ARG1 influences polyamine and proline biosynthesis via ornithine metabolism and can shape nitric oxide signaling through competition with nitric oxide synthases. Arg1 expression is prominent in hepatocytes and is also inducible in myeloid cells, where it participates in immunometabolic programs linked to inflammatory resolution and tissue remodeling. Dysregulated arginine catabolism has been associated with altered hepatic metabolism and immune microenvironment phenotypes relevant to fibrosis, tumor-associated myeloid function, and other disease-relevant contexts in mouse models.
ARG1/Arignase 1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Arg1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Arg1. 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 Arg1 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 Arg1-disrupted clones.
