An assay for alpha-1,4-glucosidase (acid maltase) activity which is deficient in Pompe's disease is described. The assay can be used to measure the enzyme in cultured skin fibroblasts, cultured amniotic cells and peripheral blood leucocytes. [U-14 C]Maltose is used as the substrate in a total assay volume of 8 microliter. The product, [U-14C]glucose, is separated from the substrate by cellulose thin-layer chromatography. The procedure permits replicate assays from 400 microliter whole blood and from amniotic cells in primary culture. Discrimination of the heterozygous Pompe state appears to be facilitated.
