Gα i-2 Double Nickase Plasmid (h): sc-400568-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Gα i-2 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
- Gα i-2 Double Nickase Plasmid (h) and Gα i-2 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting GNAI2. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Gα i-2 Antibody (L5): sc-13534

GNAI2 encodes the human heterotrimeric G protein alpha subunit Gα i-2, a GDP/GTP-regulated signal transducer that links activated GPCRs to inhibition of adenylyl cyclase and reduced cAMP production. Through coupling to GPCR-dependent pathways, Gα i-2 shapes PKA signaling, ion channel regulation, MAPK outputs, and PI3K-dependent processes, influencing chemotaxis, secretion, and proliferative responses in diverse cell types. GNAI2 activity is also integrated with receptor desensitization and trafficking via Gβγ signaling and GRK/β-arrestin networks, helping set signaling amplitude and duration. Dysregulated Gα i-2 signaling has been associated with altered immune cell migration and aberrant growth signaling contexts, supporting its study in inflammation- and oncogenesis-related mechanisms without implying clinical utility.
Gα i-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GNAI2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GNAI2. 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 GNAI2 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 GNAI2-disrupted clones.
