Nicotinic Acetylcholine Receptor alpha 2/CHRNA2 Double Nickase Plasmid (h): sc-403376-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Nicotinic Acetylcholine Receptor alpha 2/CHRNA2 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
- Nicotinic Acetylcholine Receptor alpha 2/CHRNA2 Double Nickase Plasmid (h) and Nicotinic Acetylcholine Receptor alpha 2/CHRNA2 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting CHRNA2. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Nicotinic Acetylcholine Receptor alpha 2/CHRNA2 Antibody (H-8): sc-365251

CHRNA2 encodes the α2 subunit of neuronal nicotinic acetylcholine receptors (nAChRs), ligand-gated cation channels that assemble as heteropentamers to mediate fast cholinergic neurotransmission. Upon acetylcholine or nicotinic agonist binding, α2-containing nAChRs increase Na⁺ and Ca²⁺ influx, shaping membrane excitability and activity-dependent signaling that intersects with Ca²⁺-regulated transcriptional programs and synaptic plasticity. CHRNA2 expression contributes to circuit-level modulation in the central nervous system, influencing processes such as arousal, attention, and reward-related signaling. Genetic variation and dysregulated nAChR function have been associated with neuropsychiatric phenotypes and substance use–related traits, making CHRNA2 a useful target for mechanistic studies of cholinergic pathway perturbation.
Nicotinic Acetylcholine Receptor alpha 2/CHRNA2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CHRNA2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CHRNA2. 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 CHRNA2 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 CHRNA2-disrupted clones.
