Abstract

It was observed during the course of routine casework that different bloodstains from the same individual could produce anomalies in the glyoxalase I band patterns. Blood-stains were heated at different temperatures for periods of 4 and 6 h and then examined using electrophoretic techniques. It was demonstrated that upon heating, band alterations in the glyoxalase I Type 1 phenotype can occur, causing the analyst to render the results inconclusive.
