Pannexin-1 Double Nickase Plasmid (m): sc-424967-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Pannexin-1 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
- Pannexin-1 Double Nickase Plasmid (m) and Pannexin-1 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Panx1. One or both designs may be available

Panx1 encodes pannexin-1, a large-pore membrane channel that mediates ATP and metabolite release to shape autocrine and paracrine purinergic signaling. Pannexin-1 activity is engaged downstream of P2X7 receptor stimulation and inflammatory cues, coupling membrane depolarization and caspase-associated pathways to extracellular nucleotide signaling. In mouse tissues, Panx1 contributes to immune cell activation, inflammasome-linked responses, and coordinated calcium dynamics, with additional roles in vascular tone regulation and neuroglial communication. Dysregulated PANX1-dependent ATP release has been implicated in models of neuroinflammation, ischemic injury, and aberrant cell death signaling, making Panx1 a useful target for mechanistic studies of inflammation and stress responses.
Pannexin-1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Panx1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Panx1. 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 Panx1 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 Panx1-disrupted clones.
