The obtained products were purified by metal-affine chromatography and their specificity was confirmed in immunechemical reactions with reference monoclonal antibodies. The antigenic activity of recombinant proteins was studied by indirect immune enzyme assay (IEA) with porcine serum, which had been in advance characterized by the "HerdCheck" kit (IDEXX Co.). It was shown as possible to apply the derived recombinant antigens in determining, by indirect IEA, antibodies to the PRRS virus.</p></abstract><trans-abstract xml:lang="ru"><p>С использованием бакуловирусной системы экспрессии получены рекомбинантные белки нуклеокапсида (N) американского и европейского типов вируса репродуктивного и респираторного синдрома свиней (РРСС). Полученные продукты были очищены методом метапло-аффинной хроматографии и их специфичность подтверждена в имму нохимических реакциях с использованием референтных моноклональных антител. Антигенная активность рекомбинантных белков была исследована в реакции непрямого иммуноферментного анализа (ИФА) с использованием свиных сывороток, охарактеризованных ранее коммерческим набором "HerdChek" фирмы "IDEXX".
Показана возможность применения полученных рекомбинантных антигенов для определения антител к вирусу РРСС методом непрямого иммуноферментного анализа.</p></trans-abstract><kwd-group xml:lang="en"><kwd>porcine reproductive and respiratory syndrome virus</kwd><kwd>recombinant nucleocapsid protein</kwd><kwd>expression in the baculovirus system</kwd><kwd>immunochemical characteristic</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вирус репродуктивного и респираторного синдрома свиней</kwd><kwd>рекомбинантный белок нуклеокапсида</kwd><kwd>экспрессия в бакуловирусной системе</kwd><kwd>иммунохимическая характеристика</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Albina Е., Leforban Y., Baron T. et al.
