Anti-FUT4 Antibody

This rabbit-derived polyclonal reagent from Antibodies.com targets Fucosyltransferase 4 (FUT4), the Golgi-resident enzyme responsible for synthesizing the Lewis X (CD15) trisaccharide that decorates glycoproteins and glycolipids on myeloid cells and select epithelia. Each vial contains 100 µL of unconjugated IgG suitable for Western blot, immunohistochemistry, and flow cytometry workflows, with validated reactivity against human and mouse samples. The antibody is supplied as a polyclonal antiserum raised in rabbit, offering an epitope breadth that monoclonal alternatives may miss, and it is compatible with standard secondary detection reagents for chromogenic or fluorescent readouts. Because FUT4 expression is routinely surveyed in studies of granulocyte maturation, selectin-mediated adhesion, and tumor-associated glycosylation, this reagent is well-suited for biomarker research in inflammatory and oncology contexts. Short-term storage at 4°C is acceptable for working aliquots, while long-term stability is best maintained at -20°C; avoid repeated freeze-thaw cycles by preparing single-use portions on receipt.
