For the GSSCys assays, either GSH was varied between 50 M and 2.0 mM at fixed GSSCys concentrations (25, 50, 100 and 150 M) or GSSCys was varied between 25 and 200 M at fixed concentrations of GSH (0.05, 0.1, 0.2, 0.3 and 1.0 mM for ScGrx7 or 0.3, 0.5, 1.0 and 2.0 mM for PfGrx)
It also is considered an extracellular matrix molecule because of the presence of the tripeptide RGD in the amino termini of some PSG forms.240, 250 Although the expression of PSG is more or less pregnancy specific, qualitative or quantitative assays of these proteins have not proved to be superior to the assay of hCG as a biochemical test of pregnancy
