Mouse Lgals9 encodes galectin-9, a β-galactoside–binding lectin that regulates cell–cell and cell–matrix interactions by recognizing glycosylated receptors on immune and stromal cells. Galectin-9 influences leukocyte trafficking, cytokine signaling, and immune checkpoint–associated responses, and is linked to modulation of apoptosis, autophagy, and inflammatory signaling programs. In cellular stress contexts, galectin-9 can participate in endosomal/lysosomal processes and shape the balance between immune activation and immune suppression. Dysregulated LGALS9/galectin-9 activity has been associated with autoimmune inflammation, fibrosis, and tumor immune microenvironment remodeling, supporting its study in immunology and cancer biology models.
galectin-9 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Lgals9 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Lgals9. 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 Lgals9 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 Lgals9-disrupted clones.
