Anti-ARSA Antibody

The ARSA target is a lysosomal sulfatase that hydrolyzes cerebroside sulfate, with loss-of-function variants linked to metachromatic leukodystrophy. This unconjugated rabbit polyclonal reagent from Antibodies.com is raised against arylsulfatase A and validated for western blot and immunohistochemistry workflows on human, mouse, and rat samples.

Supplied as a 100 µl aliquot at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, the antibody can be diluted directly into standard blotting and immunostaining buffers. The polyclonal format recognizes multiple epitopes on the mature enzyme and its precursor forms, which is useful when working with patient fibroblasts, brain sections, and transfected cell lines used to model sulfatide metabolism and lysosomal enzyme trafficking.
