SR-6 Double Nickase Plasmid (h): sc-402874-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- SR-6 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-6 Double Nickase Plasmid (h) and SR-6 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting HTR6. One or both designs may be available

HTR6 encodes the human 5-hydroxytryptamine receptor 6 (SR-6), a G protein–coupled receptor enriched in the central nervous system that couples primarily to Gs to stimulate adenylyl cyclase and elevate intracellular cAMP. Through cAMP/PKA-dependent signaling, SR-6 influences neuronal excitability and regulates transcriptional programs linked to synaptic plasticity and circuit modulation. The receptor also intersects with broader neuromodulatory networks that shape cognitive and affective processes, making it a useful entry point for studying serotonin-dependent signaling dynamics. Dysregulated serotonergic GPCR signaling, including pathways involving HTR6, has been associated in the literature with neuropsychiatric and neurodegenerative disease biology and with altered cognitive phenotypes in experimental models.
SR-6 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the HTR6 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within HTR6. 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 HTR6 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 HTR6-disrupted clones.
