Mucin 2/MUC2 Double Nickase Plasmid (m): sc-421751-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Mucin 2/MUC2 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
- Mucin 2/MUC2 Double Nickase Plasmid (m) and Mucin 2/MUC2 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Muc2. One or both designs may be available

Muc2 encodes mucin 2 (MUC2), a gel-forming secreted mucin that constitutes the major structural component of the intestinal mucus barrier in mice. Through extensive O-glycosylation and polymerization, MUC2 supports epithelial protection, spatial segregation of the microbiota, and regulation of mucosal immune homeostasis. Its expression and maturation are linked to goblet cell differentiation programs and secretory pathway processes including ER stress responses, while mucus layer integrity influences inflammatory signaling networks at the epithelial surface. Altered Muc2 function or expression is widely used to model barrier dysfunction and mucosal inflammation, with relevance to colitis-associated phenotypes and microbiome-driven disease mechanisms.
Mucin 2/MUC2 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Muc2 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Muc2. 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 Muc2 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 Muc2-disrupted clones.
