A Microanalytical Electrophoresis Technique for the Determination of Polymorphic Blood Proteins for Medical and Forensic Applications This paper describes the results obtained to date using an electro-phoretic technology (equipment and methodology) designed for simple, rapid, reliable, and economical determination of a number or polymorphic enzymes and proteins. The technology permits both the visualization and estimation of ng and pg quantities of enzymes and proteins. While methodology for the identification and quantification of specific blood proteins and enzymes is useful in many areas of biological research, it has practical application of particular value in medical diagnosis and in forensic science.
