Junctophilin-2 Double Nickase Plasmid (h): sc-401805-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Junctophilin-2 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
- Junctophilin-2 Double Nickase Plasmid (h) and Junctophilin-2 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting JPH2. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Junctophilin-2 Antibody (H-3): sc-377086

JPH2 encodes junctophilin-2, a structural membrane-bridging protein that stabilizes junctional membrane complexes between the plasma membrane and sarcoplasmic/endoplasmic reticulum. By tethering these membranes, junctophilin-2 helps organize excitation–contraction coupling microdomains and supports efficient calcium-induced calcium release through coordinated positioning of L-type Ca²⁺ channels and ryanodine receptors. JPH2-dependent architecture contributes to Ca²⁺ homeostasis, downstream Ca²⁺-regulated signaling, and sarcomere function in striated muscle cells. Altered JPH2 expression or function has been associated with cardiomyopathy-linked remodeling of dyads, aberrant Ca²⁺ handling, and arrhythmogenic cellular phenotypes relevant to cardiovascular disease modeling.
Junctophilin-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the JPH2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within JPH2. 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 JPH2 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 JPH2-disrupted clones.
