Abstract

Данная работа посвящена отработке и усовершенствованию метода моди- фикации МАЛДИ мишени металл-аффинными сорбентами на основе монослоев Ленгмюра, содержащими новые объекты исследования, такие как редкоземель- ные металлы (лантан, церий, европий, иттербий) для специфичного выделения хлорсодержащих аддуктов белков крови. Цель работы: исследование возможности модификации МАЛДИ мишени сорбентами на основе стеаратов лантана, церия, европия и иттербия для специфичной экстракции хлорсодержащих аддуктов белков. Задачи, которые решались в ходе исследования: 1. Модифицировать МАЛДИ мишень металл-аффинными сорбентами на ос- нове стеаратов лантана, церия, европия и иттербия; 2. Исследовать полученные сорбенты с использованием различных физико- химических методов; 3. Провести металл-аффинную экстракцию модифицированных пептидов глобина из его гидролизата. Работа была проведена на базе ФГБУН ИТ ФМБА России. Был доказан со- став каждого из полученных сорбентов, проведено исследование полученных сорбентов с помощью сканирующей электронной микроскопии, энергодисперсионной рентгеновской спектроскопии и масс-спектрометрии. Разработан новый подход для специфичного выделения из биологического образца аддуктов глобина с 2,4-дихлор-N-хлорацетанилидом.

This work is devoted to the development and improvement of the method for modifying a MALDI target with metal affinity sorbents based on Langmuir monolayers containing new research objects, such as rare-earth metals (lanthanum, cerium, europium, ytterbium) for the specific isolation of chlorine-containing adducts of blood proteins. Objective: to study the possibility of modifying the MALDI target with sorbents based on lanthanum, cerium, europium, and ytterbium stearates for specific extraction of chlorine-containing protein adducts. Tasks that were solved during the study: 1. Modify the MALDI target with metal affinity sorbents based on lanthanum, cerium, europium and ytterbium stearates; 2. Investigate the resulting sorbents using various physicochemical methods; 3. Carry out metal-affinity extraction of modified globin peptides from its hydrolyzate. The work was fulfilled on the basis of Institute of Toxicology, Federal Medical-Biological Agency of Russia. The composition of each of the obtained sorbents was proved, a study of the obtained sorbents was carried out using scanning electron microscopy, energy dispersive x-ray spectroscopy and mass spectrometry. A new approach has been developed for the specific isolation of the globin adducts from 2,4- dichloro-N-chloroacetanilide from a biological sample.
