alpha 4 Sodium Potassium ATPase/ATP1A4 Double Nickase Plasmid (h): sc-402561-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- alpha 4 Sodium Potassium ATPase/ATP1A4 Double Nickase Plasmid (h) 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
- alpha 4 Sodium Potassium ATPase/ATP1A4 Double Nickase Plasmid (h) and alpha 4 Sodium Potassium ATPase/ATP1A4 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting ATP1A4. One or both designs may be available

ATP1A4 encodes the alpha 4 catalytic subunit of the Na⁺/K⁺-ATPase, a P-type ATPase that maintains transmembrane Na⁺ and K⁺ gradients essential for membrane potential, osmotic balance, and secondary active transport. By coupling ATP hydrolysis to ion exchange, ATP1A4 influences intracellular signaling linked to ion homeostasis, cellular excitability, and epithelial transport processes. Altered Na⁺/K⁺-ATPase activity can modulate pathways involving calcium handling and downstream kinase signaling, providing a mechanistic entry point to study stress responses and ion-dependent regulation of cell physiology. Although ATP1A4 is best known for roles in reproductive biology, its ion-pumping function supports broader investigations into how pump subunits contribute to tissue-specific physiology and disease-relevant cellular phenotypes.
alpha 4 Sodium Potassium ATPase/ATP1A4 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ATP1A4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ATP1A4. 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 ATP1A4 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 ATP1A4-disrupted clones.
