Anti-NEU4 Antibody

NEU4 is a lysosomal sialidase enzyme that hydrolyzes terminal sialic acid residues from glycoproteins and glycolipids, and this unconjugated rabbit polyclonal IgG antibody from Antibodies.com is raised against that target for western blot detection in human and mouse samples. The reagent is supplied as 100 µl of polyclonal antiserum that recognizes endogenous NEU4 protein under denaturing conditions, supporting studies of sialic acid catabolism, lysosomal storage, membrane ganglioside turnover, and related pathways in cell and tissue lysates. Because the antibody is unconjugated, it can be paired with secondary reagents such as HRP- or fluorophore-labeled anti-rabbit IgG to match the detection chemistry of a given western blot protocol. Reactivity has been reported for human and mouse samples, which lets the same reagent be used for cross-species comparison of NEU4 expression in matched lysate sets. Storage is typically at -20 °C in working aliquots to limit freeze-thaw cycles of the polyclonal IgG preparation, and each vial is intended for use as a single-use reagent across western blotting experiments rather than repeated long-term storage on the bench.
