ARK-1 CRISPR/Cas9 KO Plasmid (h): sc-401568
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- ARK-1 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 ARK-1 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: ARK-1 Antibody (C-1): sc-398814

Overview
AURKA encodes ARK-1, a serine/threonine kinase that localizes to centrosomes and mitotic spindle poles to coordinate centrosome maturation, spindle assembly, and accurate chromosome segregation. ARK-1 activity is tightly regulated across the G2/M transition and interfaces with core mitotic control circuits, including PLK1- and TPX2-dependent processes, to ensure timely mitotic entry and progression. Dysregulated AURKA signaling is associated with aberrant spindle dynamics, aneuploidy, and chromosomal instability, making it broadly relevant to studies of cell cycle control, genome maintenance, and oncogenic transformation. In human cells, perturbation of ARK-1 function is commonly leveraged to dissect checkpoint responses, mitotic timing, and centrosome-driven stress pathways.
ARK-1 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the AURKA gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the AURKA 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 AURKA 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 ARK-1 protein expression.
This CRISPR knockout system enables efficient generation of AURKA-deficient cell models for investigation of ARK-1 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by ARK-1 CRISPR/Cas9 KO Plasmid (h) and ARK-1 CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the AURKA locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by ARK-1 HDR Plasmid (h) and ARK-1 HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by AURKA homology arms to support homology-directed repair at defined AURKA target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
