MMP9 Double Nickase Plasmid (m) | sc-421679-NIC | 20 µg | $410.00 |
Matrix metalloproteinase 9 (MMP9), encoded by the mouse Mmp9 gene, is a secreted zinc-dependent endopeptidase that degrades extracellular matrix components and processes bioactive molecules to regulate tissue remodeling. MMP9 activity intersects with pathways controlling leukocyte migration, cytokine and chemokine gradients, angiogenesis, and wound repair, and is frequently studied in the context of inflammatory signaling and extracellular matrix turnover. In the tumor microenvironment and during chronic inflammation, altered Mmp9 expression can influence basement membrane integrity, immune cell infiltration, and vascular permeability. Dysregulated MMP9 has been associated with mouse models of cancer progression, arthritis, neuroinflammation, and fibrotic remodeling, making it a common target for mechanistic studies of matrix-driven phenotypes.
MMP9 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Mmp9 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Mmp9. 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 Mmp9 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 Mmp9-disrupted clones.
