HAI-1 CRISPR/Cas9 KO Plasmid (h) | sc-404011 | 20 µg | $397.00 |
SPINT1 encodes hepatocyte growth factor activator inhibitor type 1 (HAI-1), a membrane-anchored Kunitz-type serine protease inhibitor that constrains pericellular proteolysis at epithelial surfaces. HAI-1 regulates the activity and maturation of proteases such as matriptase (ST14) and hepsin, thereby shaping extracellular matrix remodeling, epithelial barrier integrity, and growth factor signaling cascades including HGF/c-MET. Through these interactions, SPINT1 contributes to epithelial homeostasis, wound repair, and control of cell motility and invasion-related programs. Dysregulated SPINT1/HAI-1 balance has been linked to altered protease networks observed in epithelial pathologies, including inflammatory injury and cancer-associated remodeling.
HAI-1 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the SPINT1 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the SPINT1 together with the Streptococcus pyogenes Cas9 nuclease. The plasmids also encode GFP, allowing fluorescent identification and enrichment of successfully transfected cells by fluorescence microscopy or flow cytometry.
The multi-guide design increases the likelihood of generating insertions or deletions (indels) that disrupt the SPINT1 open reading frame following Cas9-mediated double-strand break formation. DNA breaks introduced by the CRISPR/Cas9 system are repaired through endogenous non-homologous end joining (NHEJ) pathways, frequently resulting in frameshift mutations that abolish HAI-1 protein expression.
This CRISPR knockout system enables efficient generation of SPINT1-deficient cell models for investigation of HAI-1 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.
