Abstract
- Using updated technical procedures (immobilized pH gradients for isoelectric focusing followed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis: IPG/SDS-PAGE) we provide a two-dimensional (2-D) map of amniotic fluid (AF) proteins. This map comprises over 800 silver-stained spots. Over 150 spots have been identified by matching on the net with human plasma and cerebrospinal fluid maps available from SWISS 2DPAGE database; several additional spots were assigned by immunoblotting and/or microanalytical techniques. This report details our investigation on AF proteins focusing on the 17th week of gestation, when AF is most commonly used for clinical evaluation of fetal disorders. As a whole, the map displays a number of potential markers for fetal development and for gestation abnormalities. The 2-D electrophoretic technique allows the monitoring of all these proteins at the same time along with additional spots that may prove of diagnostic significance.
