Arylsulfatase A/ARSA in Human Liver. Arylsulfatase A/ARSA was detected in immersion fixed paraffin-embedded sections of human liver using 1.7 µg/mL Human Arylsulfatase A/ARSA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2485) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Background: Arylsulfatase A/ARSA

As a member of the sulfatase family, ARSA is required for the lysosomal degradation of cerebroside-3-sulfate, a sphingolipid sulfate ester and a major constituent of the myelin sheet (1). The ARSA deficiency results in metachromatic leukodystrophy (MLD), a lysosomal storage disease in the central and peripheral nervous systems with severe and progressive neurological symptoms (2). The deduced amino acid sequence of human ARSA consists of a signal peptide (residues 1-18) and a mature chain (residues 19-507) (3). Recombinant human ARSA corresponds to the mature chain and has sulfatase activity described above.
