CYP1B1 Double Nickase Plasmid (h): sc-400907-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- CYP1B1 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
- CYP1B1 Double Nickase Plasmid (h) and CYP1B1 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting CYP1B1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: CYP1B1 Antibody (G-4): sc-374228

CYP1B1 encodes a cytochrome P450 monooxygenase that catalyzes oxidative metabolism of endogenous substrates and xenobiotics, including steroid hormones and polycyclic aromatic hydrocarbons. As part of phase I biotransformation, CYP1B1 functions downstream of aryl hydrocarbon receptor (AHR) signaling and contributes to redox homeostasis through reactive intermediate formation and detoxification pathways. Its activity influences cellular responses to environmental exposures and modulates hormone-dependent signaling networks. Altered CYP1B1 expression or function has been associated with ocular development disorders such as primary congenital glaucoma and with changes in carcinogen metabolism relevant to cancer biology research.
CYP1B1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CYP1B1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CYP1B1. 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 CYP1B1 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 CYP1B1-disrupted clones.
