   <abstract xml:lang="ru">
    <p>Поиск закономерностей и физических основ первых стадий амилоидной агрегации вот уже на протяжении десятилетий остаётся важной задачей физики белковых молекул. Существуют определённые аналогии между процессами амилоидной агрегации и кристаллизации. В обоих случаях раствор является пересыщенным, и появление затравки новой фазы приводит к лавинообразному переходу растворённого белка в кристаллы или амилоидные фибриллы. В данной работе проведено спектральное и микроскопическое исследование агрегации А-бета пептида на поверхности стекла. Экспериментально показано, что стеклянная поверхность может сорбировать молекулы А-бета пептида и тем самым приводить к увеличению их способности к агрегации, в том числе и амилоидной. Появление фазы сорбированного белка на поверхности может влиять на агрегацию пептидов в толще раствора. Необходимость учёта такого влияния является очевидной в любом исследовании белковой агрегации.</p>

    <p>Search of the physical foundations of the first stages of amyloid aggregation remains an important objective of the protein physics for a last few decades. There are certain analogies between processes amyloid aggregation and crystallization. In both cases, the solution is supersaturated, and the appearance of seed of new phase leads to a cascade of crystallization or protein amyloid fibrils formation. In this work spectral and microscopic investigation of the A-beta peptide aggregation on the glass surface ware done. It is shown experimentally that the glass surface can sorb molecules of A-beta peptide, and thereby lead to an increase in their ability to aggregate, including amyloid. The appearance of phase of protein adsorbed on the surface can affect the aggregation of peptides in bulk solution. The need for taking into account this influence is evident in any study of protein aggregation.</p>
