FucT-IX Double Nickase Plasmid (h): sc-416354-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- FucT-IX Double Nickase Plasmid (h) consists of a pair of plasmids each encoding a D10A mutated Cas9 nuclease and a target-specific 20 nt guide RNA (gRNA) designed to knockout gene expression with greater specificity than its CRISPR/Cas9 KO counterpart
- Paired gRNA sequences are offset by approximately 20 bp to allow for specific Cas9-mediated double nicking of the genomic DNA, which mimics a DSB
- One plasmid in the pair contains a puromycin-resistance gene for selection; the other plasmid in the pair contains a GFP marker to visually confirm transfection
- FucT-IX Double Nickase Plasmid (h) and FucT-IX Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting FUT9. One or both designs may be available

FUT9 encodes the human α1,3-fucosyltransferase FucT-IX, a Golgi-resident enzyme that catalyzes fucose transfer to N-acetyllactosamine acceptors to generate Lewis-type fucosylated glycans. Through regulation of terminal fucosylation, FUT9 influences glycosylation-dependent processes including cell–cell recognition, adhesion molecule function, and modulation of receptor and glycolipid glycan structures. FUT9 activity contributes to the biosynthesis of Lewis X–related epitopes, linking it to pathways that shape immune interactions and developmental cell signaling. Dysregulated fucosylation patterns involving FUT9 have been studied in contexts such as inflammation-associated glycan remodeling and altered glycosylation signatures observed in cancer biology.
FucT-IX Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FUT9 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FUT9. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt FUT9 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of FUT9-disrupted clones.
