IMMUNOLOGIC STUDIES OF WATER-SOLUBLE HUMAN AMYLOID FIBRILS

Abstract
Eight preparations of soluble amyloid and degraded amyloid (DAM) were compared immunologically. Unlike amyloid fibrils, six of eight preparations of DAM proved to be relatively strong immunogens. Antisera to DAM reacted weakly or not at all with normal human serum or extracts of normal tissues, but were specifically reactive with amyloid fibrils or DAM.
