Trypsin-1 CRISPR/Cas9 KO Plasmid (h): sc-401128
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Trypsin-1 CRISPR/Cas9 Knockout (KO) Plasmid (h) is a pool of plasmids, each encoding Cas9 nuclease and a target-specific 20 nt guide RNA (gRNA) designed for maximum knockout efficiency using sequences derived from the GeCKO v2 library
- gRNA sequences direct Cas9 to induce site-specific double-strand breaks (DSBs) in the Trypsin-1 genomic locus, resulting in gene knockout through non-homologous end joining (NHEJ)
- The puromycin resistance and RFP genes are flanked by LoxP sites, enabling removal of selection markers via Cre recombinase (Cre Vector: sc-418923) after establishing stable knockout cell lines

Overview
PRSS1 encodes trypsin-1, a secreted serine protease synthesized as trypsinogen and activated in the gastrointestinal tract to cleave peptide substrates and initiate proteolytic cascades. Its activity contributes to digestive enzyme activation and can modulate extracellular proteolysis, with downstream effects on epithelial barrier function and inflammatory signaling. Dysregulated trypsin-1 activation and PRSS1 variants are linked to pancreatitis biology, including premature zymogen activation, acinar cell stress responses, and tissue injury mechanisms. PRSS1 is therefore a useful entry point for studying protease-driven pathways and genotype-to-phenotype relationships in pancreatic and gastrointestinal research models.
Trypsin-1 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the PRSS1 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the PRSS1 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 PRSS1 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 Trypsin-1 protein expression.
This CRISPR knockout system enables efficient generation of PRSS1-deficient cell models for investigation of Trypsin-1 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by Trypsin-1 CRISPR/Cas9 KO Plasmid (h) and Trypsin-1 CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the PRSS1 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by Trypsin-1 HDR Plasmid (h) and Trypsin-1 HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by PRSS1 homology arms to support homology-directed repair at defined PRSS1 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
