Gα 13 Double Nickase Plasmid (h): sc-401180-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Gα 13 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 13 Double Nickase Plasmid (h) and Gα 13 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting GNA13. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Gα 13 Antibody (6F6-B5): sc-293424

GNA13 encodes the human heterotrimeric G protein alpha subunit Gα13, a key transducer of signals from GPCRs that couple to the G12/13 family. Upon activation, Gα13 engages RhoGEFs to stimulate RhoA-dependent pathways that regulate actin cytoskeletal remodeling, cell adhesion, migration, and contractility, with downstream effects on transcriptional programs and mechanotransduction. This signaling axis intersects with pathways controlling vascular tone, platelet activation, and immune cell trafficking, and it is frequently studied in the context of oncogenic GPCR signaling and altered cell motility. Dysregulated GNA13 activity has been associated with aberrant Rho signaling and disease-relevant phenotypes such as invasive behavior and disrupted tissue architecture in model systems.
Gα 13 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GNA13 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GNA13. 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 GNA13 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 GNA13-disrupted clones.
