GABP-α Double Nickase Plasmid (h): sc-417668-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- GABP-α 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
- GABP-α Double Nickase Plasmid (h) and GABP-α Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting GABPA. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: GABP-α Antibody (G-1): sc-28312

GABPA encodes GA-binding protein alpha (GABP-α), an ETS family DNA-binding transcription factor that heterodimerizes with GABPB subunits to regulate promoter and enhancer activity. It integrates signals controlling mitochondrial biogenesis and oxidative phosphorylation programs, including nuclear-encoded respiratory chain genes, and contributes to cell-cycle progression and differentiation through transcriptional network coordination. GABP-α also participates in chromatin- and promoter-associated regulation of genes involved in immune and stress-response pathways. Dysregulation of GABPA-dependent transcription has been linked to altered metabolic states and proliferative phenotypes observed across multiple disease-relevant cellular contexts, supporting its use as a mechanistic node for pathway interrogation.
GABP-α Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GABPA locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GABPA. 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 GABPA 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 GABPA-disrupted clones.
