Lysosomal enzyme levels in human amniotic fluid cells in tissue culture. IV. %A N-acetyl-beta-D-glucosaminidase.

Abstract

Total and % A hexosaminidase were similar for primary cultures and later passages of amniotic fluid cells. The culture variables-through serial passage, within a passage and replicate primary cultures-resulted in some variation in total hexosaminidase, but an insignificant change in % A hexosaminidase. They are unlikely to give rise to any problems in the antenatal diagnosis of Sandhoff's and Tay-Sachs diseases.
