TWIK-2 Double Nickase Plasmid (h): sc-407263-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- TWIK-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
- TWIK-2 Double Nickase Plasmid (h) and TWIK-2 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting KCNK6. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: TWIK-2 Antibody (H-6): sc-376515

Human KCNK6 encodes TWIK-2, a two-pore domain potassium (K2P) channel that contributes to background K+ conductance and helps set resting membrane potential and membrane excitability. By shaping ionic homeostasis, TWIK-2 influences stimulus–secretion coupling, cell volume regulation, and Ca2+-dependent signaling processes in excitable and non-excitable cells. Altered K2P channel activity has been linked to dysregulated vascular tone, inflammatory signaling, and proliferation-related phenotypes, making KCNK6 a relevant target for mechanistic studies of ion channel contributions to cardiometabolic and immune-associated pathways. TWIK-2 function is commonly investigated in the context of electrophysiological readouts, intracellular signaling dynamics, and pathway-level perturbation analyses.
TWIK-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the KCNK6 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within KCNK6. 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 KCNK6 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 KCNK6-disrupted clones.
