SR-2A Double Nickase Plasmid (h): sc-401532-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- SR-2A 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
- SR-2A Double Nickase Plasmid (h) and SR-2A Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting HTR2A. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: SR-2A Antibody (A-4): sc-166775

HTR2A encodes the serotonin receptor 2A (SR-2A), a G protein-coupled receptor that primarily couples to Gq/11 to activate phospholipase C, increase intracellular Ca²⁺ signaling, and stimulate PKC-dependent phosphorylation cascades. SR-2A signaling interfaces with MAPK/ERK pathways and modulates gene expression programs that influence neuronal excitability, synaptic plasticity, and cortical circuit activity. In human tissues, HTR2A expression and receptor signaling are frequently studied in the context of neurotransmission and neuromodulatory network regulation. Altered SR-2A pathway activity and regulatory variation in HTR2A have been associated in research literature with neuropsychiatric phenotypes and treatment-response variability, supporting its relevance for mechanistic studies of serotonergic signaling.
SR-2A Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the HTR2A locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within HTR2A. 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 HTR2A 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 HTR2A-disrupted clones.
