LGALS1 encodes galectin-1, a β-galactoside–binding lectin that regulates cell–cell and cell–matrix interactions by recognizing glycosylated receptors and extracellular matrix components. Galectin-1 influences adhesion, migration, and apoptosis, and modulates immune and stromal signaling through glycan-dependent clustering of surface proteins. It participates in processes linked to tumor–microenvironment crosstalk, angiogenesis, and immune regulation, and altered LGALS1 expression has been reported across multiple inflammatory and cancer-associated contexts. These features make galectin-1 a useful node for studying glycosylation-dependent signaling and extracellular cues that shape cell fate.
galectin-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the LGALS1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within LGALS1. 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 LGALS1 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 LGALS1-disrupted clones.
