CD155 Double Nickase Plasmid (m): sc-424585-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- CD155 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
- CD155 Double Nickase Plasmid (m) and CD155 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Pvr. One or both designs may be available

Mouse Pvr encodes CD155 (poliovirus receptor/nectin-like molecule 5), an immunoglobulin superfamily adhesion molecule that localizes at cell–cell contacts and participates in cytoskeletal remodeling, migration, and tissue organization. CD155 engages immune receptors including DNAM-1 (CD226), TIGIT, and CD96, shaping NK and T cell signaling at the interface of adhesion and immune surveillance. Through roles in adhesion dynamics and immune checkpoint–like interactions, Pvr is frequently studied in contexts of inflammation, tumor immunology, and viral entry mechanisms. Its expression and receptor-binding properties provide a tractable node for dissecting crosstalk between cellular motility programs and immune regulation in mouse models.
CD155 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Pvr locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Pvr. 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 Pvr 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 Pvr-disrupted clones.
