Abstract: | Fifteen primary amniotic fluid cultures were established from a single sample of amniotic fluid. Three different methods were used to set up these cultures which yielded 13 cell strains. Nine lysosomal enzymes (acid phosphatase, β-glucuronidase, β-galactosidase, α-galactosidase, α-glucosidase, α-mannosidase, α-arabinosidase, and arylsulphatase A) were assayed in these 13 cell strains. The coefficients of variation of these enzyme levels were less than the coefficients for enzyme levels in cell strains grown from different samples of amniotic fluid but greater than those for the combined culture and assay system used. No assay values were found which could have suggested a possible enzyme deficiency disease. |
