the two populations of particles contained acid hydrolases ( phosphatase , six glycosidases and four cathepsins ) in roughly equal proportions , displayed latency , had similar turnover of 35s-mucopolysaccharide in normal as well as in iduronidase-deficient cells , and were recipients of alpha-l-iduronidase , previously shown to be acquired by receptor-mediated endocytosis .
