Abstract
THE lactic dehydrogenase (LDH) agent, detectable by increased levels of plasma or serum LDH in inoculated test mice, was found in association with a variety of transplanted murine tumours by Riley et al.1. Various estimations of its size by filtration methods have been suggested. These include diameters of 2 mµ, approximately 45 mµ, and 55 mµ (refs. 2, 3 and 4, respectively). In an attempt to resolve these conflicting observations, electron microscopic investigations of the LDH agent were initiated, and this report describes preliminary findings.
