  • Title: Use of 4-methylumbelliferyl-6-sulpho-2-acetamido-2-deoxy-beta- D-glucopyranoside for prenatal diagnosis of Tay-Sachs disease using chorionic villi.
    Author: Grebner EE, Wenger DA.
    Journal: Prenat Diagn; 1987 Jul; 7(6):419-23. PubMed ID: 2958791.
    Abstract:
    Prenatal diagnosis of Tay-Sachs disease was performed using the sulphated substrate 4-methylumbelliferyl-6-sulpho-2-acetamido-2-deoxy-beta-D-glucopyranoside to detect hexosaminidase A in chorionic villi. The presence or absence of hexosaminidase A in villi was detected by both a quantitative enzyme assay, and by a rapid, novel procedure which permitted visual discrimination between normal and affected villi.
