[Immunoelectrophoresis used for identification of blood stains in forensic medicine].

Conclusive evidence was obtained in this study that immunoelectrophoresis could be used in the identification of blood-stains in two particular cases: for diagnosis or approach to diagnosis of the age of a blood-stain, and for diagnosis of the human origin of a blood-stain that had been treated with petroleum products. Although many aspects should be investigated in more detail, it is certain that this method can be employed in combination with other methods.
