CSN8 CRISPR/Cas9 KO Plasmid (m): sc-430844
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- CSN8 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 CSN8 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
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: CSN8 Antibody (C-9): sc-514088

Overview
Cops8 encodes CSN8, a core subunit of the COP9 signalosome that regulates cullin-RING E3 ubiquitin ligases by controlling cullin neddylation status and thereby influencing ubiquitin-dependent protein turnover. Through this activity, CSN8 contributes to proteostasis, cell-cycle progression, DNA damage responses, and stress-adaptive signaling by modulating the stability of key regulatory proteins. Disruption of COP9 signalosome function has been linked to altered inflammatory signaling, impaired development and tissue homeostasis, and dysregulated apoptosis, making Cops8 relevant for mechanistic studies of pathways that couple ubiquitin regulation to cellular fitness. In mouse models, perturbation of CSN components is frequently associated with defects in growth control and organ function, supporting its use in investigating disease-relevant cellular phenotypes without implying therapeutic outcomes.
CSN8 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Cops8 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Cops8 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 Cops8 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 CSN8 protein expression.
This CRISPR knockout system enables efficient generation of Cops8-deficient cell models for investigation of CSN8 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by CSN8 CRISPR/Cas9 KO Plasmid (m) and CSN8 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Cops8 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by CSN8 HDR Plasmid (m) and CSN8 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Cops8 homology arms to support homology-directed repair at defined Cops8 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
