FucT-IX CRISPR/Cas9 KO Plasmid (m): sc-420427
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- FucT-IX 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 FucT-IX 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 Fut9 encodes fucosyltransferase IX (FucT-IX), a Golgi-resident α1,3-fucosyltransferase that catalyzes terminal fucosylation of N-glycans and glycolipids, contributing to synthesis of Lewis-type epitopes such as Lewis X. This glycosylation activity modulates cell–cell adhesion, receptor trafficking, and signal transduction by shaping the glycan-dependent interactions of membrane proteins and extracellular ligands. Fut9-dependent fucosylation is frequently studied in the context of developmental programs and immune-related processes where glycan motifs regulate leukocyte adhesion and tissue patterning. Dysregulated fucosylation patterns and altered Lewis antigen expression are also used as molecular readouts in models of inflammation and oncogenic transformation without implying clinical utility.
FucT-IX CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Fut9 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Fut9 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 Fut9 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 FucT-IX protein expression.
This CRISPR knockout system enables efficient generation of Fut9-deficient cell models for investigation of FucT-IX signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by FucT-IX CRISPR/Cas9 KO Plasmid (m) and FucT-IX CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Fut9 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by FucT-IX HDR Plasmid (m) and FucT-IX HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Fut9 homology arms to support homology-directed repair at defined Fut9 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
