CELA1 encodes elastase-1, a secreted serine protease that cleaves elastin and other extracellular matrix proteins, contributing to proteolytic remodeling of connective tissue. As part of the pancreatic elastase family, elastase-1 participates in regulated protease activity and can influence extracellular matrix turnover, cell–matrix signaling, and inflammatory processes through the release of bioactive matrix fragments. Dysregulated elastase activity has been linked to pathways involved in tissue injury and repair, including protease–antiprotease balance and remodeling programs relevant to pulmonary and vascular biology. CELA1 is therefore studied in contexts where extracellular proteolysis shapes barrier function, inflammation, and structural integrity of tissues.
Elastase-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CELA1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CELA1. 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 CELA1 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 CELA1-disrupted clones.
