Anti-NEU1 antibodies are used in the immunodetection of the protein neuraminidase 1. In humans, the canonical protein has a reported length of 415 amino acid residues and a mass of 45.5 kDa. Its subcellular localization is in the cytoplasmic vesicles, lysosomes, and cell membrane. It is reported to be highly expressed in the pancreas, followed by skeletal muscle, kidney, placenta, heart, lung and liver. A member of the Glycosyl hydrolase 33 protein family, NEU1 is known to catalyze the removal of sialic acid (N-acetylneuraminic acid) moieties from glycoproteins and glycolipids. Synonyms for this target antigen include NEU, SIAL1, sialidase-1, G9 sialidase, N-acetyl-alpha-neuraminidase 1, and NANH. NEU1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of NEU1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
