Sedimentation Behavior of Serum Lactic Dehydrogenase

Abstract

Lactic dehydrogenase from serum of an apparently health}7 individual, sera from two patients with myelogenous leukemia, and lysed erythrocytes behaved as an essentially monodisperse compound, sedimenting at a rate which is in good agreement with that reported for the crystalline enzyme obtained from other sources. It will be necessary to employ other methods to determine conclusively whether serum LDH activity is attributable to one or more components.
