IL-9 CRISPR/Cas9 KO Plasmid (m): sc-421119
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- IL-9 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 IL-9 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 Il9 encodes interleukin-9 (IL-9), a pleiotropic cytokine predominantly produced by Th9 cells that modulates immune cell proliferation, differentiation, and survival. IL-9 signals through the IL-9 receptor complex to activate JAK/STAT pathways, with prominent STAT5-dependent transcriptional programs that shape cytokine networks and tissue inflammation. In murine systems, IL-9 influences mast cell and eosinophil biology, mucosal barrier responses, and airway immune remodeling, linking it to allergic inflammation and immune dysregulation. Altered IL-9 activity is frequently studied in models of asthma-like airway inflammation, helminth-driven immunity, and tumor-associated immune microenvironments.
IL-9 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Il9 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Il9 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 Il9 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 IL-9 protein expression.
This CRISPR knockout system enables efficient generation of Il9-deficient cell models for investigation of IL-9 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by IL-9 CRISPR/Cas9 KO Plasmid (m) and IL-9 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Il9 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by IL-9 HDR Plasmid (m) and IL-9 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Il9 homology arms to support homology-directed repair at defined Il9 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
