Dicer Double Nickase Plasmid (m): sc-431380-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Dicer 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
- Dicer Double Nickase Plasmid (m) and Dicer Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Dicer1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Dicer Antibody (F-10): sc-136979

Mouse Dicer1 encodes Dicer, an RNase III endonuclease that processes precursor microRNAs and long double-stranded RNAs into ~21–23 nt small RNAs that load into Argonaute-containing RISC complexes. Through miRNA and endo-siRNA biogenesis, Dicer shapes post-transcriptional gene regulation programs that influence cell-cycle progression, differentiation, innate immune signaling, and maintenance of genome stability. Dicer-dependent small RNA pathways are central to RNA interference, epigenetic regulation, and suppression of transposable elements. Altered Dicer activity and disrupted miRNA homeostasis are associated with developmental defects and disease-relevant phenotypes in cancer biology, neurobiology, and immune dysregulation studies.
Dicer Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Dicer1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Dicer1. 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 Dicer1 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 Dicer1-disrupted clones.
