Notum CRISPR/Cas9 KO Plasmid (m): sc-429545
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Notum 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 Notum 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
Notum encodes a secreted carboxylesterase that attenuates Wnt signaling by deacylating the palmitoleate group on Wnt ligands, thereby reducing ligand–receptor engagement and downstream β-catenin–dependent transcription. In mouse, NOTUM contributes to regulation of embryonic patterning, tissue homeostasis, and stem cell niche activity through modulation of canonical Wnt/Frizzled–LRP signaling. Altered NOTUM activity has been linked to dysregulated Wnt pathway output in contexts such as bone remodeling, intestinal epithelial dynamics, and neurodevelopmental processes. As a Wnt pathway brake, Notum is frequently studied in pathway feedback regulation and microenvironmental control of proliferation and differentiation.
Notum CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Notum gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Notum 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 Notum 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 Notum protein expression.
This CRISPR knockout system enables efficient generation of Notum-deficient cell models for investigation of Notum signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

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