Assessment of Third Trimester Choline Phosphotransferase Activity in Uncomplicated Human Pregnancies

Abstract

Summary10 min. One half milliliter of the butanol phase was transferred to CDP-choline:1,2-diglyceride choline phosphotransferase (CPT; EC 2.7.8.2) undergoes a marked surge in activity in human amniotic fluid when assayed from 30 weeks of gestation to term. The activity of this enzyme, plotted against gestational age, follows a highly significant regression correlation from which an equation can be obtained for the prediction of gestational age.
