SCCA1/2 CRISPR/Cas9 KO Plasmid (h) | sc-418018 | 20 µg | $397.00 |
SERPINB4 encodes squamous cell carcinoma antigen 1/2 (SCCA1/2), a clade B serine protease inhibitor that modulates intracellular proteolysis by inhibiting select cathepsins and related proteases. By restraining protease-driven protein turnover and inflammatory protease activity, SCCA1/2 influences epithelial differentiation, barrier-associated stress responses, and cytokine-linked signaling programs. Altered SERPINB4 expression has been reported in squamous epithelia and inflammatory microenvironments, where it is used as a biomarker in studies of tumor biology and chronic inflammation. Functional interrogation of SERPINB4 supports mechanistic work on protease–antiprotease balance, cell survival under stress, and crosstalk between epithelial and immune pathways.
SCCA1/2 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the SERPINB4 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the SERPINB4 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 SERPINB4 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 SCCA1/2 protein expression.
This CRISPR knockout system enables efficient generation of SERPINB4-deficient cell models for investigation of SCCA1/2 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.
