SPNS2 Double Nickase Plasmid (m): sc-432145-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- SPNS2 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
- SPNS2 Double Nickase Plasmid (m) and SPNS2 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Spns2. One or both designs may be available

Spns2 encodes SPNS2, a multipass membrane transporter that exports sphingosine-1-phosphate (S1P) to establish extracellular gradients essential for S1P receptor signaling. In mouse tissues, SPNS2-dependent S1P distribution regulates lymphocyte trafficking, vascular maturation, and endothelial barrier function, integrating lipid metabolism with immune and angiogenic pathways. Disruption of SPNS2 perturbs S1P-mediated signaling networks that influence inflammation, vascular permeability, and organ-specific immune surveillance. These functions make Spns2 a useful target for studying lipid mediator transport, receptor-driven signaling cascades, and mechanisms underlying immune dysregulation and vascular pathobiology in experimental models.
SPNS2 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Spns2 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Spns2. 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 Spns2 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 Spns2-disrupted clones.
