Centrin-2 Double Nickase Plasmid (h): sc-400867-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Centrin-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
- Centrin-2 Double Nickase Plasmid (h) and Centrin-2 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting CETN2. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Centrin-2 Antibody (3F8): sc-293192

CETN2 encodes centrin-2, a conserved EF-hand calcium-binding protein that localizes to centrosomes and basal bodies, where it supports centriole duplication, centrosome cohesion, and cilia-associated microtubule organization. Centrin-2 participates in cell cycle–linked control of microtubule nucleation and spindle assembly, and it contributes to genome stability through centrosome homeostasis and interactions with DNA repair-associated factors. Disruption of centrosome integrity and ciliogenesis pathways connected to centrin function is frequently associated with chromosomal instability and proliferative phenotypes relevant to cancer biology. CETN2 is therefore widely used as a marker and mechanistic node in studies of centrosome dynamics, cell division fidelity, and cilium-related cellular processes.
Centrin-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CETN2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CETN2. 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 CETN2 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 CETN2-disrupted clones.
