IFN-α9 CRISPR/Cas9 KO Plasmid (m): sc-421045
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- IFN-α9 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 IFN-α9 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
Ifna9 encodes mouse interferon-α9 (IFN-α9), a type I interferon cytokine induced by innate immune sensing of viral and microbial nucleic acids. IFN-α9 signals through the IFNAR receptor complex to activate JAK1/TYK2 and downstream STAT1/STAT2-IRF9 (ISGF3), driving transcription of interferon-stimulated genes that restrict pathogen replication and reshape antigen presentation. This pathway modulates dendritic cell activation, macrophage polarization, and T and B cell responses, linking IFN-α9 to inflammation control and immune homeostasis. Dysregulated type I interferon signaling is implicated in chronic inflammatory and autoimmune phenotypes and contributes to immunopathology in infection models, making Ifna9 a useful node for mechanistic studies in mouse systems.
IFN-α9 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Ifna9 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Ifna9 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 Ifna9 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 IFN-α9 protein expression.
This CRISPR knockout system enables efficient generation of Ifna9-deficient cell models for investigation of IFN-α9 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by IFN-α9 CRISPR/Cas9 KO Plasmid (m) and IFN-α9 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Ifna9 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by IFN-α9 HDR Plasmid (m) and IFN-α9 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Ifna9 homology arms to support homology-directed repair at defined Ifna9 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
