title: The specific assay of arylsulphatase C, a rat liver microsomal marker enzyme.
abstract: Conditions based on previous assays with potassium p-acetylphenyl sulphate have been established for the specific assay of arylsulphatase C in rat tissues. The enzyme has optimum activity with 40mm substrate at pH8.0 in the presence of 0.1m-phosphate buffer. Under these conditions arylsulphatase C can be assayed without interference from the other arylsulphatase enzymes present and is useful as a marker for the endoplasmic reticulum in cell-fractionation studies.
