By means of starch gel electrophoresis and an improved staining technique for the demonstration of isoenzyme bands, placental alkaline phosphatase types were demonstrated in placenta tissue and birth blood traces, which had been stored for several days at room temperature. This method was successfully applied in a case of infanticide and secret delivery to identify the mother of the child. The results of a study on a Japanese population are also reported.
