Nkx-2.3 Double Nickase Plasmid (h): sc-406709-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Nkx-2.3 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
- Nkx-2.3 Double Nickase Plasmid (h) and Nkx-2.3 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting NKX2-3. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Nkx-2.3 Antibody (4F4): sc-517182

NKX2-3 encodes the homeobox transcription factor Nkx-2.3, a nuclear DNA-binding regulator that patterns endoderm-derived tissues and helps maintain intestinal and lymphoid organ identity. By controlling lineage-specific transcriptional programs, Nkx-2.3 influences epithelial differentiation, mucosal immune organization, and regional vascular development, integrating with broader developmental signaling networks that shape gut homeostasis. Altered NKX2-3 activity has been linked to dysregulated gene expression in intestinal inflammation and immune-associated phenotypes, making it a relevant node for studying mechanisms that connect developmental regulators to mucosal immunity. Its transcriptional targets and context-dependent activity support investigation of gene regulatory circuits in gut epithelium and stromal-immune compartments.
Nkx-2.3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the NKX2-3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within NKX2-3. 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 NKX2-3 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 NKX2-3-disrupted clones.
