title: Complementation analysis of beta-galactosidase deficiency by means of histochemical method.
abstract: Cultured skin fibroblasts from 4 beta-galactosidase-deficient patients with different clinical features were hybridized and beta-galactosidase activities were measured using 4-methylumbelliferyl (4MU)-derivate and by means of indigogenic method. Compared with the assays of beta-galactosidase activity using 4MU-derivate, more clear-cut evidence was obtained in the indigogenic method for a judgement of complementation.
