Dkk-3 Double Nickase Plasmid (m): sc-424494-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Dkk-3 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
- Dkk-3 Double Nickase Plasmid (m) and Dkk-3 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Dkk3. One or both designs may be available

Dickkopf-related protein 3 (Dkk-3) is a secreted glycoprotein that modulates extracellular signaling, with context-dependent effects on Wnt/β-catenin activity and broader crosstalk with pathways governing cell fate decisions. In mouse tissues, Dkk3 expression has been linked to regulation of proliferation, differentiation, and tissue remodeling, including effects on stromal–epithelial interactions and immune microenvironments. Altered Dkk3 levels are reported across multiple disease-relevant contexts such as tumor biology, fibrosis, and metabolic or cardiovascular remodeling, where shifts in Wnt-associated transcriptional programs can influence cell state transitions. These features make Dkk3 a useful node for dissecting paracrine signaling and pathway dynamics in mechanistic models.
Dkk-3 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Dkk3 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Dkk3. 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 Dkk3 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 Dkk3-disrupted clones.
