Множественность копий мтДНК в клетке обеспечивает высокую чувствительность таких методик. Высокая чувствительность ПЦР, выявляющих мтДНК курицы (Gallus gallus), может приводить к положительному результату при анализе продукции, содержащей куриные яйца. Однако ряд мясных изделий, в частности, некоторые вареные колбасы, не содержат мясо убоя курицы, при этом при их приготовлении используют куриные яйца или меланж. Методики, в основе которых лежит ПЦР, выявляющая мтДНК, не способны отличить добросовестное следование рецептуре от фальсификации мясного состава таких изделий более дешёвым куриным мясом. В данной работе мы осуществили дизайн ПЦР «в реальном времени», целевыми последовательностями которой являются ядерные последовательности. Отдельной задачей был подбор праймеров для ПЦР, служащей для внутреннего контроля, где целевыми последовательностями являются ядерные последовательности, консервативные для животных и птиц. Мы показали, что использование уникальных хромосомных последовательностей в качестве целевых последовательностей позволяет избавиться от положительных результатов в ПЦР, где в качестве матрицы используется ДНК, выделенная из куриных яиц или меланжа. Методика на основе разработанных ПЦР может быть использована для выявления фальсификации состава смешанных мясных изделий мясом убоя курицы.</p></abstract><trans-abstract xml:lang="en"><p>Laboratory PCR techniques used to control the quality of meat products typically detect mitochondrial DNA sequences (mtDNA). The multiplicity of mtDNA copies in the cell provides such PCR techniques a high sensitivity. The high sensitivity of PCR detecting chicken mtDNA can lead to a positive result when applied to analyze mixed meat products containing chicken eggs. Many meat products, particularly some cooked sausages, do not contain chicken meat, while their recipes include chicken eggs or melange. In such cases, PCR detecting mtDNA cannot distinguish correctly the recipe ingredients from the food fraud with cheaper chicken meat. In this work, we carried out a design of realtime PCR which uses nuclear sequences as a target. A separate task was to select primers for PCR for internal control, for which we selected a nuclear sequence conserved for animals and birds as a target. Here we show that using a unique nuclear sequence as a target sequence allows getting rid of positive results in PCR, when the template is DNA, isolated from chicken eggs or mélange. The designed real-time PCR can be used in protocols applied to detect the falsification of the mixed meat products by chicken meat.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ПЦР в реальном времени</kwd><kwd>фальсификация пищевой продукции</kwd><kwd>Gallus gallus</kwd></kwd-group><kwd-group xml:lang="en"><kwd>real-time PCR</kwd><kwd>food fraud</kwd><kwd>Gallus gallus</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">Фомина Т.
