γ-GCSc Double Nickase Plasmid (h): sc-401133-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- γ-GCSc 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
- γ-GCSc Double Nickase Plasmid (h) and γ-GCSc Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting GCLC. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: γ-GCSc Antibody (H-5): sc-390811

GCLC encodes the catalytic subunit of glutamate–cysteine ligase (γ-GCSc), the rate-limiting enzyme in glutathione biosynthesis that catalyzes formation of γ-glutamylcysteine. By controlling cellular glutathione pools, γ-GCSc supports redox homeostasis, detoxification of electrophiles, and maintenance of mitochondrial and cytosolic antioxidant capacity, with downstream effects on ROS-sensitive signaling and metabolic adaptation. GCLC activity is tightly regulated in oxidative stress response pathways, including NRF2/KEAP1-driven transcriptional programs, and influences susceptibility to ferroptosis and other stress-induced cell death mechanisms. Dysregulation of GCLC-dependent glutathione metabolism has been linked to altered responses to oxidative stress and xenobiotics in contexts such as liver disease, neurodegeneration, and cancer biology.
γ-GCSc Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GCLC locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GCLC. 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 GCLC 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 GCLC-disrupted clones.
