Application

Anti-ARSA antibody is suitable for co-immunoprecipitation, co-localization and flow cytometry.Anti-ARSA antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

ARSA (arylsulfatase A) requires post-translational modification to become catalytically active. This involves the oxidation of the -CH2SH group of a cysteine residue to aldehyde. Lack of this modification results in inactive enzyme, which causes the lysosomal storage disorder called multiple sulfatase deficiency. Complete or partial inactivation of this gene leads to Metachromatic leukodystrophy (MLD), which is a lysosomal storage disease. It is characterized by the accumulation of cerebroside sulfate in lysosomes. ARSA pseudo-deficiency is caused in individuals who are homozygous for the allele, which results in significant loss of ARSA activity. However, the activity is sufficient for normal cerebroside catabolism and results in clinically healthy phenotype.

Features and Benefits

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.Every Prestige Antibody is tested in the following ways: IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues. Protein array of 364 human recombinant protein fragments.

General description

ARSA (arylsulfatase A) is a lysosomal sulfatase. This gene maps to human chromosome 22q13. This protein exists as a dimer and has a molecular weight of 107kDa. It is an acidic glycoprotein. It consists of 507 amino acid residues. Placental arylsulfatase A contains a putative 18 amino acid long signal peptide, preceding its N- terminal. ARSA is predicted to have three N-glycosylation sites.
