Enzyme replacement therapy (ERT) has proven to be an effective therapy for some lysosomal storage disorder (LSD) patients. A potential complication during ERT is the generation of an immune response against the replacement protein. We have investigated the antigenicity of two distantly related glycosidases, alpha-glucosidase (Pompe disease or glycogen storage disease type II, GSD II), and alpha-L-iduronidase (Hurler syndrome, mucopolysaccharidosis type I, MPS I). The linear sequence epitope reactivity of affinity purified polyclonal antibodies to recombinant human alpha-glucosidase and alpha-L-iduronidase was defined, to both glycosidases. The polyclonal antibodies exhibited some cross-react..
