Contactin 3 CRISPR/Cas9 KO Plasmid (m): sc-422111
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Contactin 3 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 Contactin 3 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
Cntn3 encodes contactin 3, a GPI-anchored immunoglobulin superfamily cell-adhesion molecule enriched in the nervous system that supports neurite outgrowth, axon guidance, and synapse organization. Contactin 3 participates in contactin–L1 family and receptor interactions at the neuronal surface, shaping cell–cell recognition and circuit assembly during development and maturation. Through roles in adhesion-dependent signaling and membrane microdomain organization, CNTN3 influences connectivity and plasticity programs relevant to neurodevelopmental and neuropsychiatric phenotypes. Mouse Cntn3 is therefore a useful entry point for dissecting molecular determinants of wiring specificity and activity-dependent network remodeling.
Contactin 3 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Cntn3 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Cntn3 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 Cntn3 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 Contactin 3 protein expression.
This CRISPR knockout system enables efficient generation of Cntn3-deficient cell models for investigation of Contactin 3 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by Contactin 3 CRISPR/Cas9 KO Plasmid (m) and Contactin 3 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Cntn3 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by Contactin 3 HDR Plasmid (m) and Contactin 3 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Cntn3 homology arms to support homology-directed repair at defined Cntn3 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
