NHE-1 Double Nickase Plasmid (h): sc-400748-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- NHE-1 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
- NHE-1 Double Nickase Plasmid (h) and NHE-1 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting SLC9A1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: NHE-1 Antibody (54): sc-136239

SLC9A1 encodes the plasma membrane Na+/H+ exchanger NHE-1, a key regulator of intracellular pH, cell volume, and sodium homeostasis. By extruding protons in exchange for extracellular sodium, NHE-1 supports pH-sensitive processes including cytoskeletal remodeling, focal adhesion dynamics, and cell motility, and it interfaces with MAPK signaling, Rho-family GTPase pathways, and ion-transport networks. NHE-1 activity influences epithelial and cardiac physiology, neuronal excitability, and cellular responses to osmotic and metabolic stress. Dysregulated SLC9A1/NHE-1 function has been implicated in contexts such as ischemia-related injury biology, hypertension-associated remodeling, cancer cell invasion phenotypes, and neurodegenerative stress responses, making it a useful node for mechanistic studies.
NHE-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SLC9A1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SLC9A1. 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 SLC9A1 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 SLC9A1-disrupted clones.
