cyclin F Double Nickase Plasmid (m): sc-419514-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- cyclin F Double Nickase Plasmid (m) 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
- cyclin F Double Nickase Plasmid (m) and cyclin F Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Ccnf. One or both designs may be available

Mouse Ccnf encodes cyclin F, an F-box protein that serves as the substrate-recognition component of the SCF (SKP1–CUL1–F-box) E3 ubiquitin ligase complex and links cell-cycle progression to ubiquitin-dependent proteostasis. Cyclin F helps coordinate S/G2 and G2/M transitions by targeting specific regulators of DNA replication and mitotic entry for proteasomal turnover, thereby influencing genome stability and checkpoint control. Through these functions it intersects with pathways governing replication stress responses, centrosome homeostasis, and DNA damage signaling. Dysregulation of cyclin F–mediated ubiquitination has been associated with impaired cell-cycle control and neurodegeneration-related mechanisms, supporting its relevance in studies of proliferative disorders and neuronal vulnerability.
cyclin F Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Ccnf locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Ccnf. 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 Ccnf 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 Ccnf-disrupted clones.
