PDE5A Double Nickase Plasmid (h): sc-401627-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- PDE5A 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
- PDE5A Double Nickase Plasmid (h) and PDE5A Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting PDE5A. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: PDE5A Antibody (D-3): sc-398747

PDE5A encodes phosphodiesterase 5A, a cGMP-specific phosphodiesterase that terminates nitric oxide–cGMP signaling by hydrolyzing cyclic GMP to GMP. By controlling cGMP levels, PDE5A regulates protein kinase G (PKG) activity and downstream processes including smooth muscle tone, vascular reactivity, platelet function, and cardiac remodeling responses. PDE5A activity links to signaling networks that integrate guanylate cyclase output with calcium handling and cytoskeletal dynamics, influencing cellular contractility and proliferation. Dysregulated PDE5A expression or signaling balance has been investigated in cardiovascular and pulmonary vascular pathophysiology, fibrosis-related remodeling, and other contexts where altered cGMP homeostasis contributes to disease-relevant phenotypes.
PDE5A Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the PDE5A locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within PDE5A. 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 PDE5A 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 PDE5A-disrupted clones.
