Experimental data analysis demonstrates that in case of the extract that contains protein-peptidic complexes in different molecular weights range, the Kingsley-Weichselbaum method shows the highest quality of protein concentration determination; while studying highmolecular weight fraction (more than 30 kDa), it is possible to obtain more information by combining the spectrophotometric method and the Kingsley-Weichselbaum method. Low-molecular weight fractions (less than 30 kD) should be investigated by complex methods including the spectrophotometric method, Lowry and Bradford methods. These methods make it possible to presumably estimate protein molecules size ranges (by amount of peptide bonds), and also to determine hydrophobic and aromatic amino acids presence.</p></abstract><trans-abstract xml:lang="ru"><p>В данной статье приведены данные сравнительного анализа четырех методов количественной оценки содержания белково-пептидных комплексов в  экстрактах, полученных на основе сырья животного происхождения, а  также низкомолекулярных и высокомолекулярных фракциях экстракта: прямого спектрофотометрического определения при длинах волн 260 и 280 нм с последующим расчетом по формуле Калькара; биуретовой реакции по методу Кингслея — Вейксельбаума; с использованием реактива Брэдфорда и по стандартному методу Лоури. Анализ полученных экспериментальных данных показал, что в  случае с  экстрактом, содержащим белково-пептидные комплексы в  различном диапазоне молекулярных масс наиболее качественно показывает концентрацию белка метод Кингслея-Вейксельбаума, при исследовании высокомолекулярной фракции (более 30 кДа) больше информации возможно получить при сочетании спектрофотометрического метода и также метода Кингслея-Вейксельбаума. Низкомолекулярные (менее 30 кДа) фракции следует исследовать комплексно, с  применением спектрофотометрического метода, методов Лоури и  Брэдфорда. Данные методы дают возможность предположительно оценить диапазоны размеров белковых молекул (по числу пептидных связей), а также определить наличие гидрофобных и ароматических аминокислот.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>белки</kwd><kwd>пептиды</kwd><kwd>экстракция</kwd><kwd>спектро-фотометрия</kwd><kwd>метод Брэдфорд</kwd><kwd>метод Лоури</kwd><kwd>метод Кингслея — Вейксельбаума</kwd><kwd>биуретовая реакция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>proteins</kwd><kwd>peptides</kwd><kwd>extraction</kwd><kwd>spectrophotometry</kwd><kwd>Bradford assay</kwd><kwd>Lowry’s assay</kwd><kwd>Kingsley-Weixelbaum assay</kwd><kwd>biuret reaction</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Noble, J.E.
