fetuin-B Double Nickase Plasmid (m): sc-425597-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- fetuin-B 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
- fetuin-B Double Nickase Plasmid (m) and fetuin-B Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Fetub. One or both designs may be available

Mouse Fetub encodes fetuin-B, a secreted glycoprotein of the cystatin superfamily that circulates in plasma and is expressed by hepatocytes and other tissues. Fetuin-B modulates extracellular protease activity and participates in proteostasis at the cell surface and in the extracellular milieu, influencing processes such as matrix remodeling and reproductive biology. Altered fetuin-B abundance has been linked in the literature to metabolic and inflammatory states and to fertility-associated phenotypes, making Fetub a useful locus for studying systemic regulation of protease networks. In biomedical research, Fetub provides a tractable model for investigating liver-derived secreted factors that couple metabolic pathways with tissue homeostasis.
fetuin-B Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Fetub locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Fetub. 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 Fetub 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 Fetub-disrupted clones.
