Superoxide Dismutase 1/SOD1 Double Nickase Plasmid (h): sc-400186-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Superoxide Dismutase 1/SOD1 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
- Superoxide Dismutase 1/SOD1 Double Nickase Plasmid (h) and Superoxide Dismutase 1/SOD1 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting SOD1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Superoxide Dismutase 1/SOD1 Antibody (G-11): sc-17767

SOD1 encodes the cytosolic Cu/Zn superoxide dismutase that catalyzes dismutation of superoxide radicals to hydrogen peroxide and oxygen, forming a primary line of defense against oxidative stress. By controlling reactive oxygen species flux, SOD1 influences redox homeostasis, mitochondrial function, and downstream signaling pathways that couple oxidative burden to inflammation, proteostasis, and cell survival programs. Dysregulated SOD1 activity or stability is linked to altered antioxidant capacity and aggregation-prone states that perturb motor neuron and glial biology. As a result, SOD1 is widely studied in neurodegeneration, redox-sensitive metabolic remodeling, and cellular stress-response networks.
Superoxide Dismutase 1/SOD1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SOD1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SOD1. 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 SOD1 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 SOD1-disrupted clones.
