Input: Abstract: A procedure for the multisystem analysis of bloodstains using the simultaneous separation of the enzymes glyoxalase I, esterase D, and phosphoglucomutase has been developed. The amount of bloodstain required has therefore been reduced threefold without any loss in resolution and sensitivity. Bloodstains at least seven weeks old have been correctly phenotyped in all three systems.
