ПЦР широко применяется для детекции патогенов бактериальной и вирусной природы. Праймеры являются очень важным компонентом ПЦР, поскольку специфичность амплификации зависит в первую очередь от них. Они необходимы для работы фермента и являются специфичными к фрагменту интереса. По итогам отбора нуклеотидных последовательностей генома или отдельных фрагментов РНК вируса из международной базы данных на сайте NCBI, было выявлено большое количество последовательностей для вируса лейкоза крупного рогатого скота, которые хранятся в банках генов и ежедневно пополняющихся новыми данными. Конструирование праймеров с соблюдением необходимых параметров проводится с помощью различных компьютерных программ, основными из которых являются MUSCLE, UGENE V.36.0, Primer-BLAST, Oligo Analyzer и другие. Сконструированные праймеры затем синтезировали на синтезаторе олигонуклеотидов Expedite 8909, согласно инструкции прилагаемой к прибору. В результате проведенных опытов нами были подобраны и синтезированы специфические синтетические олигонуклеотиды env (g51) _1 и env (g51) _2, для постановки ПЦР при лейкозе крупного рогатого скота.</p></abstract><trans-abstract xml:lang="en"><p>the polymerase chain reaction (PCR) method is widely used to solve various problems. PCR is widely used for the detection of bacterial and viral pathogens. Primers are a very important component of PCR, since the specificity of amplification depends primarily on them. They are necessary for the enzyme to work and are specific to the fragment of interest. Based on the results of the selection of nucleotide sequences of the genome or individual fragments of the virus RNA from the international database on the NCBI website, a large number of sequences for the bovine leukemia virus were identified, which are stored in gene banks and updated daily with new data. The construction of primers in compliance with the necessary parameters is carried out using various computer programs, the main of which are MUSCLE, UGENE V.36.0, Primer-BLAST, Oligo Analyzer and others. The designed primers were then synthesized on the Expedite 8909 oligonucleotide synthesizer, according to the instructions attached to the device. As a result of our experiments, we selected and synthesized specific synthetic oligonucleotides env (g51)_1 and env (g51)_2, for setting up PCR for bovine leukemia.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вирус лейкоза крупного рогатого скота</kwd><kwd>праймер</kwd><kwd>ген</kwd><kwd>нуклеотиды</kwd><kwd>полимеразная цепная реакция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bovine leukemia virus: primer</kwd><kwd>gene</kwd><kwd>nucleotides</kwd><kwd>polymerase chain 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">ICTV International Committee on Taxonomy of Viruses (ICTV).
