ECE-1 Double Nickase Plasmid (h): sc-402379-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- ECE-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
- ECE-1 Double Nickase Plasmid (h) and ECE-1 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting ECE1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: ECE-1 Antibody (A-6): sc-376017

ECE1 encodes endothelin-converting enzyme 1 (ECE-1), a membrane-bound zinc metalloprotease that cleaves big endothelins to generate bioactive endothelin peptides, thereby shaping endothelin receptor signaling. Through regulation of endothelin-mediated vasoconstriction, endothelial function, and smooth muscle tone, ECE-1 contributes to pathways controlling vascular homeostasis and inflammatory responses. ECE-1 also intersects with extracellular peptide processing in the secretory and endosomal systems, influencing local peptide availability and receptor activation dynamics. Altered ECE1 activity or expression has been associated with cardiovascular and pulmonary vascular remodeling phenotypes, renal and metabolic dysregulation, and tumor-associated microenvironment signaling in multiple model systems.
ECE-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ECE1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ECE1. 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 ECE1 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 ECE1-disrupted clones.
