EphA7 Double Nickase Plasmid (m): sc-420197-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- EphA7 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
- EphA7 Double Nickase Plasmid (m) and EphA7 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Epha7. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: EphA7 Antibody (E-7): sc-393973

Epha7 encodes EphA7, a receptor tyrosine kinase in the ephrin–Eph family that mediates contact-dependent signaling to regulate cell positioning, boundary formation, and axon guidance during development. Upon ephrin ligand engagement, EphA7 activates pathways involving Rho family GTPases, MAPK signaling, and cytoskeletal remodeling, shaping migration and adhesion programs. In the nervous system, EphA7 contributes to neural circuit assembly and synaptic organization, and altered Eph/ephrin signaling has been linked to defects in neurodevelopmental patterning and dysregulated tissue architecture. Because Eph receptors also influence proliferation and differentiation decisions, Epha7 is frequently studied in contexts where cell–cell communication and spatial organization impact disease-relevant phenotypes.
EphA7 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Epha7 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Epha7. 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 Epha7 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 Epha7-disrupted clones.
