Abstract

Описан способ/анализ для детекции различных агрегированных форм амилоидного пептида с использованием амилоидоспецифического спектроскопического зонда, такого как конго красный и родственные аналоги. Такой анализ может быть использован для оценки агрегационного состояния данного пептида в присутствии других потенциальных ингибиторов фибриллогенеза, что позволяет получить ценную модель, посредством которой могут быть протестированы ингибиторы агрегации в in vitro-моделях. Результаты такого анализа могут быть использованы для определения стадии, на которой процесс агрегации может быть прекращен для снижения токсичности амилоидного полипептида по отношению к нервным клеткам. В конкретных примерах показано, что для оценки агрегационных форм β-амилоидного пептида может быть использована спектроскопия кругового дихроизма, Уф-абсорбционная спектроскопия и флуоресцентная спектроскопия.Отчет о международном поиске был опубликован 2001.10.18.
