Trypsin-2 CRISPR/Cas9 KO Plasmid (m): sc-423519
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Trypsin-2 CRISPR/Cas9 Knockout (KO) Plasmid (m) 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-2 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
Prss2 encodes trypsin-2, a secreted serine protease produced as a zymogen and activated in proteolytic cascades that regulate digestion and extracellular protein processing in the mouse pancreas. Beyond nutrient proteolysis, trypsin-2 can influence tissue remodeling and inflammatory signaling by activating other proteases and modulating protease-activated receptor pathways, with downstream effects on epithelial integrity and innate immune responses. Dysregulated trypsin activity is linked to pancreatic acinar stress, aberrant protease activation, and inflammatory injury, making Prss2 a relevant node for studying exocrine pancreas physiology and protease-driven pathology. Mouse Prss2 models support mechanistic work on proteostasis, secretory pathway burden, and protease network interactions in pancreatic and gastrointestinal contexts.
Trypsin-2 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Prss2 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Prss2 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 Prss2 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-2 protein expression.
This CRISPR knockout system enables efficient generation of Prss2-deficient cell models for investigation of Trypsin-2 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by Trypsin-2 CRISPR/Cas9 KO Plasmid (m) and Trypsin-2 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Prss2 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by Trypsin-2 HDR Plasmid (m) and Trypsin-2 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Prss2 homology arms to support homology-directed repair at defined Prss2 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
