FucT-III/V/VI Double Nickase Plasmid (h): sc-401521-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- FucT-III/V/VI 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-III/V/VI Double Nickase Plasmid (h) and FucT-III/V/VI Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting FUT3. One or both designs may be available

FUT3 encodes an α1,3/4-fucosyltransferase (FucT-III/V/VI) that catalyzes terminal fucosylation of glycans to generate Lewis antigens, including sialyl-Lewis structures on glycoproteins and glycolipids. These fucosylated epitopes regulate cell–cell recognition, leukocyte–endothelial adhesion, and selectin-mediated trafficking, linking FUT3 activity to glycan biosynthesis pathways within the Golgi apparatus. Variation in FUT3-dependent glycosylation contributes to interindividual differences in Lewis blood group antigen expression and can modulate mucosal host–microbe interactions and inflammatory signaling. Dysregulated fucosylation patterns are frequently studied in the context of altered adhesion, invasion, and immune evasion phenotypes observed in diverse disease models.
FucT-III/V/VI Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FUT3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FUT3. 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 FUT3 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 FUT3-disrupted clones.
