中文摘要
使用几种策略开发了QHTS检测方法。首先,使用体外转录和翻译系统来直接评估nsp1对核糖体翻译的功能影响。第二种包括以细胞为基础的分析,以不同的形式有条件地表达NSP1蛋白,包括先前设计的符合报告细胞系,以允许任何感兴趣的蛋白质,这里是SARS-CoV2 NSP1,特定地整合到包含可诱导的符合报告系统的基因组背景中。最后,将通过使用重组生物素化NSP1的基于SPR的检测来验证对与NSP1结合的候选化合物的直接生物物理评估。
英文摘要
qHTS assays have been developed using several strategies. The first, uses an in vitro transcription and translation system to directly assess the functional effect of nsp1 on ribosomal translation. The second encompass cell-based assays conditionally expressing the nsp1 protein in different formats, including a coincidence reporter cell lines previously designed to allow a site-specific integration of any protein of interest, here SARS-CoV2 Nsp1 into a genomic background containing an inducible coincidence reporter system. Finally, direct biophysical assessment of candidate compound binding to nsp1 will be verified with a SPR-based assay using recombinant biotinylated nsp1.
