N-Ras Double Nickase Plasmid (h): sc-400180-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- N-Ras 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
- N-Ras Double Nickase Plasmid (h) and N-Ras Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting NRAS. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: N-Ras Antibody (F155): sc-31

Human NRAS encodes N-Ras, a membrane-associated small GTPase that cycles between GDP- and GTP-bound states to transmit signals from receptor tyrosine kinases to downstream effector pathways. N-Ras regulates RAF–MEK–ERK and PI3K–AKT signaling, influencing cell-cycle progression, differentiation, cytoskeletal dynamics, and survival programs. Dysregulated NRAS signaling, including activating mutations, is frequently implicated in oncogenic transformation and altered lineage specification across multiple tumor contexts. As a central node in growth factor signaling, NRAS is widely studied in pathway rewiring, feedback regulation, and resistance mechanisms in cell models.
N-Ras Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the NRAS locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within NRAS. 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 NRAS 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 NRAS-disrupted clones.
