Upon RNA isolation from primary human coronary artery endothelial cells, we performed reverse transcription-qPCR (RT-qPCR) utilising SYBR Green chemistry to measure the expression of the following genes: IL1B, IL6, CXCL8, IL12A, IL23A, PECAM1, VWF, KDR, FAPA, ACTA2, SMTN, VIM, COL4A1, MMP2, SNAI2, TWIST1, ZEB1, SCARF1, CD36, LDLR, VLDLR, VCAM1, ICAM1, SELE, SELP, CDH5, IL1R1, IL1R2, TNFRSF1A, TNFRSF1B, NOS3, PXDN.

Reaction efficiency did not correlate with the Beacon Designer rating, yet being associated with length and GC content of the reverse primer. Abovementioned correlation coefficients ranged from 0.4 to 0.5 or from -0.4 to -0.5 indicative of moderate positive or negative correlation. Other parameters did not affect reaction efficiency and coefficient of determination. Conclusion Primer parameters do not define qPCR efficiency and coefficient of determination significantly if primers are designed according to the optimised PRIMER-BLAST settings. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кПЦР</kwd><kwd>ампликон</kwd><kwd>дизайн праймеров</kwd><kwd>эффективность кПЦР</kwd><kwd>коэффициент детерминации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>qPCR</kwd><kwd>Amplicon</kwd><kwd>Primer design</kwd><kwd>Efficiency</kwd><kwd>Coefficient of determination</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при поддержке комплексной программы фундаментальных научных исследований СО РАН в рамках фундаментальной темы НИИ КПССЗ № 0546-2019-0002 «Патогенетическое обоснование разработки имплантатов для сердечно-сосудистой хирургии на основе биосовместимых материалов с реализацией пациент-ориентированного подхода с использованием математического моделирования, тканевой инженерии и геномных предикторов».</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">Chuang, L.-Y., Cheng, Y.-H., Yang, C.-H.
