Abstract

Crude amyloid enhancing factor (AEF) was extracted from brain samples of patients with Alzheimer’s disease (AD) and showed to be capable of inducing amyloidosis. This crude AEF extract was electrophoresed and seven fractions of different molecular weights were isolated by electroelution. Only two out of these seven fractions were found to have AEF activity; one fraction contained high molecular weight proteins (> 90 kDa) and the other was of lower molecular weight (21.5 to 30 kDa). These two fractions could induce accelerated amyloid deposition in experimental animals.
