KV1.5 CRISPR/Cas9 KO Plasmid (h): sc-404341
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- KV1.5 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 KV1.5 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: KV1.5 Antibody (A-3): sc-377110

Overview
KCNA5 encodes the human voltage-gated potassium channel subunit KV1.5, a delayed-rectifier K+ channel that conducts the ultrarapid delayed rectifier current (IKur) and shapes membrane repolarization and excitability. KV1.5 activity influences action potential duration, refractory properties, and Ca2+-dependent signaling by controlling membrane potential in electrically active cells, linking it to broader ion homeostasis and electrophysiological remodeling pathways. Altered KCNA5 expression or channel function has been associated with atrial electrophysiology changes and arrhythmia-related phenotypes, and it is also studied in contexts where K+ flux modulates proliferation and migration. As a result, KCNA5 is frequently investigated in mechanisms of atrial remodeling, channelopathies, and signaling networks sensitive to membrane potential dynamics.
KV1.5 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the KCNA5 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the KCNA5 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 KCNA5 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 KV1.5 protein expression.
This CRISPR knockout system enables efficient generation of KCNA5-deficient cell models for investigation of KV1.5 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by KV1.5 CRISPR/Cas9 KO Plasmid (h) and KV1.5 CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the KCNA5 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by KV1.5 HDR Plasmid (h) and KV1.5 HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by KCNA5 homology arms to support homology-directed repair at defined KCNA5 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
