GABAA Rα1 Double Nickase Plasmid (h): sc-401038-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- GABAA Rα1 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
- GABAA Rα1 Double Nickase Plasmid (h) and GABAA Rα1 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting GABRA1. One or both designs may be available

GABRA1 encodes the human GABA\(_A\) receptor α1 subunit, a core component of pentameric ligand-gated chloride channels that mediate fast inhibitory neurotransmission in the central nervous system. Through assembly with β and γ subunits, GABA\(_A\) Rα1 shapes channel gating kinetics, synaptic receptor localization, and neuronal network excitability downstream of GABAergic synapse signaling. Its activity influences processes such as synaptic plasticity, oscillatory circuit function, and excitation–inhibition balance. Genetic and functional alterations in GABRA1 have been linked to neurodevelopmental and seizure-associated phenotypes, supporting its relevance for mechanistic studies of inhibitory signaling dysfunction.
GABAA Rα1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GABRA1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GABRA1. 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 GABRA1 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 GABRA1-disrupted clones.
