connexin 37 CRISPR/Cas9 KO Plasmid (m): sc-420559
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- connexin 37 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 connexin 37 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
Mouse Gja4 encodes connexin 37 (Cx37), a gap junction protein that assembles into intercellular channels enabling direct exchange of ions and small metabolites to coordinate tissue homeostasis. Cx37 contributes to contact-dependent signaling that shapes endothelial and smooth muscle behavior, with roles in vascular development, barrier regulation, and mechanotransduction. Through gap junctional intercellular communication, it influences processes such as cell-cycle control, migration, and inflammatory signaling. Altered connexin 37 function has been associated with vascular dysfunction and cardiovascular-relevant phenotypes, supporting its use in models of angiogenesis, thrombosis-related pathways, and immune–vascular crosstalk.
connexin 37 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Gja4 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Gja4 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 Gja4 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 connexin 37 protein expression.
This CRISPR knockout system enables efficient generation of Gja4-deficient cell models for investigation of connexin 37 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by connexin 37 CRISPR/Cas9 KO Plasmid (m) and connexin 37 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Gja4 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by connexin 37 HDR Plasmid (m) and connexin 37 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Gja4 homology arms to support homology-directed repair at defined Gja4 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
