Anti-Arylsulfatase A antibodies are used for the immunodetection of the protein encoded by the ARSA gene. In humans, the canonical protein has a reported length of 507 amino acid residues and a mass of 53.6 kDa. Its subcellular localization is in the ER and lysosomes. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Sulfatase protein family, it is known to be involved with the metabolism of lipids. Post-translational modifications have been described, including glycosylation. The gene encoding this protein is implicated in Metachromatic leukodystrophy. Other names for this target antigen include MLD, cerebroside-sulfatase, epididymis secretory sperm binding protein, and ASA. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of Arylsulfatase A antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
