Материалы и методы. Протокол для генотипирования 181946C&gt;T, 191C&gt;A и -216G/T был уточнен в соответствии с ранее представленными данными. Продукты полимеразной цепной реакции (ПЦР) размером 197 bp детектировали с помощью электрофореза в 2%-м агарозном геле с последующим окрашиванием этидиум бромидом. Результаты. Наборы реактивов Biomaster HS Taq-PCR Color 2× и Biomaster LR HS PCR 2× были эффективны для амплификации 181946 G/A, локализованной в интроне гена EGFR. Кроме того, полиморфизмы -191 C/A (rs712829) и -216G/T (rs712829), расположенные в промоторном участке и содержащие чрезвычайно высокое количество GC, успешно амплифицировались с помощью набора Biomaster LR HS PCR 2×. Заключение. В настоящем исследовании показано, что наборы реактивов Biomaster HS Taq-PCR Color 2× и Biomaster LR HS PCR 2× эффективны для амплификации 181946 G/A, локализованного в интроне гена EGFR. Кроме того, EGFR SNP -191 C/A, локализованный в промоторном участке с крайне высоким содержанием GC-пар, успешно амплифицировался с помощью набора реактивов Biomaster LR HS PCR 2x.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To conduct a comparative analysis of two available kits that contain all necessary reagents and additives in a single reaction mixture, including 100 mM Tris-НCl, 100 mM KCL, 4 mM MgSO4, 0.2% of Tween 20, for the amplification of the three most common EGFR (epidermal growth factor receptor) gene polymorphisms in patients with non-small cell lung cancer (NSCLC): 181946 G/A (rs2293347), -191 C/A (rs712830) and -216G/T (rs712829). Materials and methods. The protocol for genotyping 181946C&gt;T, 191C&gt;A and -216G/T was refined according to previously reported data. Polymerase chain reaction (PCR) products measuring 197 bp were detected using electrophoresis in a 2% agarose gel, followed by staining with ethidium bromide. Results. The Biomaster HS Taq-PCR Color 2× and Biomaster LR HS PCR 2× reagent kits were effective for amplification of 181946 G/A polymorphism located in the intron of the EGFR gene. Additionally, polymorphisms -191 C/A (rs712829) and -216G/T (rs712829), located in the promoter region and containing a high GC content, were successfully amplified using the Biomaster LR HS PCR 2× kit. Conclusion. The present study shows that the Biomaster HS Taq-PCR Color 2× and Biomaster LR HS PCR 2× reagent kits are effective for amplification of 181946 G/A polymorphism located in the intron of the EGFR gene. Furthermore, the EGFR SNP -191 C/A, located in the promoter region with a high GC content, was successfully amplified using the Biomaster LR HS PCR 2× reagent kit. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>добавки</kwd><kwd>амплификация</kwd><kwd>EGFR</kwd><kwd>НМРЛ</kwd><kwd>полиморфизм</kwd><kwd>ПЦР</kwd><kwd>реагенты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>additives</kwd><kwd>amplification</kwd><kwd>EGFR</kwd><kwd>NSCLC</kwd><kwd>polymorphism</kwd><kwd>PCR</kwd><kwd>reagents</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Эта работа частично поддерживалась Министерством образования, науки и технологического развития Республики Сербия (№ 451-03-137/2025-03/200111,  451-03-136/2025- 03/200378).</funding-statement><funding-statement xml:lang="en">This study was partially supported by the Ministry of Education, Science and Technological Development of the Republic of Serbia.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Liu W., Innocenti F., Wu M.H., Desai A.A., Dolan M.E., Cook E.H. et al.
