CENP-S CRISPR/Cas9 KO Plasmid (h): sc-417249
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- CENP-S 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 CENP-S 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
CENPS encodes centromere protein S (CENP-S), a conserved component of the constitutive centromere-associated network that supports kinetochore integrity and accurate chromosome segregation. CENP-S participates in centromere and kinetochore assembly and contributes to genome stability by promoting proper mitotic progression. Disruption of centromere and kinetochore pathways is closely linked to chromosomal instability and aneuploidy, processes frequently investigated in the context of cancer biology and proliferative stress. CENP-S is also studied at the intersection of replication-associated DNA damage responses and mitotic fidelity, where defects can sensitize cells to genotoxic perturbations.
CENP-S CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the CENPS gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the CENPS 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 CENPS 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 CENP-S protein expression.
This CRISPR knockout system enables efficient generation of CENPS-deficient cell models for investigation of CENP-S signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

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