摘要：

Some amyloid-derived peptides show their toxic effects only after a long "aging" period performed several days at pH 7.4 and 37 degreesC far cluster formation. Our experiments show that long aging of beta -amyloid[25-35] under physiological conditions results in peptide band cleavage between Asn(27) and Lys(28). Relatively short incubation time (24 hours) and absence of Ca2+ ions prevent peptide cleavage and results in good aggregation of beta -amyloids.
