P2X4 Double Nickase Plasmid (m): sc-422092-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- P2X4 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
- P2X4 Double Nickase Plasmid (m) and P2X4 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting P2rx4. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: P2X4 Antibody (D-3): sc-518167

Mouse P2rx4 encodes the ATP-gated cation channel P2X4, a ligand-gated ion channel that mediates rapid Na⁺ and Ca²⁺ influx in response to extracellular ATP. P2X4 contributes to purinergic signaling that shapes membrane excitability, intracellular calcium-dependent pathways, and downstream kinase and transcriptional responses in immune and neural cell types. It is linked to microglial activation and neuroinflammatory signaling, and has been studied in contexts including neuropathic pain mechanisms, synaptic modulation, vascular regulation, and inflammatory responses. These biology features make P2rx4 a useful target for investigating ATP-driven cell communication and calcium-dependent signaling networks in mouse models.
P2X4 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the P2rx4 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within P2rx4. 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 P2rx4 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 P2rx4-disrupted clones.
