Diagnosis of Pompe's disease using pyridylamino-maltooligosaccharides as substrates of alpha-1,4-glucosidase.
We have developed a sensitive method for the assay of alpha-1,4-glucosidase in cultured skin fibroblasts and muscle tissue using pyridylamino-maltooligosaccharides as fluorescent substrates. This method is useful for the diagnosis of Pompe's disease.
