GABAA Rβ2 Double Nickase Plasmid (h): sc-405041-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- GABAA Rβ2 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 Rβ2 Double Nickase Plasmid (h) and GABAA Rβ2 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting GABRB2. One or both designs may be available

GABRB2 encodes the human γ-aminobutyric acid type A receptor β2 subunit (GABAA Rβ2), a core component of ligand-gated chloride channels that mediate fast inhibitory neurotransmission in the central nervous system. By assembling with other GABAA receptor subunits, GABAA Rβ2 influences receptor trafficking, synaptic clustering, and channel gating properties that shape neuronal excitability and network oscillations. GABRB2 function is integrated with inhibitory synapse organization, postsynaptic signaling, and activity-dependent plasticity, linking it to pathways controlling excitation–inhibition balance. Genetic or functional perturbation of GABRB2 has been associated with neurodevelopmental and neuropsychiatric phenotypes, including seizure susceptibility, making it relevant for mechanistic studies of inhibitory circuit dysfunction.
GABAA Rβ2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GABRB2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GABRB2. 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 GABRB2 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 GABRB2-disrupted clones.
