Molecular diagnostics of potato infections with PVY and PLRV by immunochromatography

Abstract: Для молекулярной диагностики инфекций картофеля Y-вирусом и вирусом скручива-ния листьев картофеля (ВСЛК) разработаны иммунохроматографические тест-системы. Чтобы размножить антиген -капсидный белок труднодоступного флоэмно-ограничен-ного ВСЛК, был создан бинарный вектор, содержащий кДНК рекомбинантной РНК то-бамовируса, в которой ген капсидного белка был заменен на ген белка оболочки ВСЛК. Рекомбинантная тобамовирусная РНК упаковывалась белком оболочки ВСЛК в сфери-ческие вирусные частицы. Химерный вирус был … Show more

“…The obtained 15-fold improvement of LFIA sensitivity is superior compared with the variants of silver enhancement reported in previous works: 10-fold increase for ochratoxin A (Anfossi et al, 2013), Helicobacter pylori (Byzova et al, 2015), and Ralstonia solanacearum (Panferov et al, 2016); 4-fold increase for cadmium (Xing et al, 2014); 3-fold increase for prostate-specific antigen (Rodriguez et al, 2016); 2.5-fold increase for fumonisin B1; and 2-fold increase for deoxynivalenol (Yu et al, 2015). Compared to other techniques of PLRV detection, the proposed silver-enhanced LFIA is more sensitive than previously-described LFIAs in conventional format with an LOD of 30 ng/mL (Kondakova, Butenko, Skurat, & Drygin, 2016) and more rapid than tissue print immunoassay with a duration of 4-5 h (Samsatly, Jawhari, Najjar, Sobh, & Abou-Jawdah, 2014). Moreover, due to possibility of on-site application, this LFIA is a good alternative for PLRV assays based on reverse transcription polymerase chain reactions (Cating, Funke, Kaur, Hamm, & Frost, 2015;Ju, 2011;Zhang et al, 2017) or loop-mediated isothermal amplification (Ahmadi, Almasi, Fatehi, Struik, & Moradi, 2013;Almasi, Manesh, Jafary, & Dehabadi, 2013).…”
