nm23-H1 Double Nickase Plasmid (m): sc-421911-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- nm23-H1 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
- nm23-H1 Double Nickase Plasmid (m) and nm23-H1 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Nme1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: nm23-H1 Antibody (NM301): sc-465

Nme1 encodes nm23-H1, a nucleoside diphosphate kinase that helps balance cellular NTP pools and supports energy-dependent processes such as cytoskeletal dynamics, vesicle trafficking, and nucleotide metabolism. In mouse cells, nm23-H1 has been linked to regulation of cell motility and adhesion programs and can influence signaling networks associated with stress responses and differentiation. Altered nm23-H1 activity is frequently studied in the context of tumor biology, where changes in metastatic behavior and invasive potential have been reported across model systems. These properties make Nme1 a useful locus for probing pathways that connect nucleotide homeostasis to migration and growth control.
nm23-H1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Nme1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Nme1. 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 Nme1 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 Nme1-disrupted clones.
