Electrophoretic Pattern of Lactic Dehydrogenase in Carriers and Patients with Duchenne Muscular Dystrophy
THE electrophoretic pattern of the enzyme lactic dehydrogenase (LDH) is composed of several bands. These bands are believed to be different molecular forms of the enzyme and have been called `isozymes'1. It has been suggested that these isozymes result from various tetrameric associations of two sub-units A and B2,3 for which there is some experimental evidence4. The pattern of LDH isozymes is tissue specific5, though the pattern in fœtal tissues is usually different from that found in adult tissues6,7.
