Abstract
The dinitrosalicylic acid reaction for measuring reducing sugar has been evaluated and found suitable for determining the saccharogenic activity of human serum. The sensitivity and reproducibility of the modified dinitrosalicylic acid method permits quantitation of the electrophoretic and chromatographic distribution of human serum amylase. Such fractionations suggest that a majority, if not all, saccharogenic activity in normal and certain abnormal specimens is chromatographically separable from other serum protein and exhibits an electrophoretic mobility similar to γ-globulin.
