title: Polyclonal antibodies against iduronate 2-sulphate sulphatase from human urine.
abstract: Human iduronate 2-sulphate sulphatase (EC 3.1.6.-) from urine has been purified by affinity chromatography on concanavalin A-Sepharose, ammonium sulphate fractionation and DEAE-cellulose chromatography. With ion-exchange chromatography, the enzyme was resolved in two activity peaks. The less anionic of these forms was further purified by polyacrylamide gel electrophoresis under non-denaturing conditions. Anti-iduronate 2-sulphate sulphatase antibodies were obtained from mice immunized with polyacrylamide eluted enzyme. The specificity of the antibodies towards iduronate 2-sulphate sulphatase was demonstrated by immunoprecipitation of the enzyme from partially purified urine protein. The procedure described in this work opens the way to the application of hybridoma technology to iduronate 2-sulphate sulphatase.
