Anti-ST3GAL4 Antibody

This rabbit polyclonal antibody from Antibodies.com targets ST3GAL4, a Golgi-resident beta-galactoside alpha-2,3-sialyltransferase that transfers sialic acid to terminal galactose residues on glycoproteins and glycolipids. The unconjugated reagent is supplied as 100 µl of polyclonal antisera raised in rabbit and is validated for Western blot and immunofluorescence workflows. It recognizes the human and rat ST3GAL4 protein in cell lysates and tissue sections, supporting research on glycosylation patterns, selectin-ligand biosynthesis, and aberrant sialylation in oncology and inflammation models. Storage at 4 °C is recommended for short-term use, with aliquoting advised to preserve stability across multiple experiments. On standard SDS-PAGE immunoblots, the antibody produces a band consistent with the predicted molecular weight of the sialyltransferase, and it performs reliably on fixed-cell immunofluorescence protocols. Researchers investigating tumor glycobiology, immune cell trafficking, or comparative glycotranscriptomic analyses will find this reagent useful for confirming ST3GAL4 expression across model systems.
