Title: Robust neutralization assay based on SARS-CoV-2 S-bearing vesicular stomatitis virus (VSV) pseudovirus and ACE2-overexpressed BHK21 cells Document date: 2020_4_9
ID: fvjh3g7v_7
Snippet: Recently, Michael Letko et al. used VSVdG-luc bearing SARS-spike chimeras to study the cell entry and receptor usage for SARS-CoV-2 and other lineage B betacoronaviruses [13] . Jianhui Nie et al. have successfully constructed a pseudovirus neutralization assay for SARS-CoV-2, which consist of pseudotyped VSV bearing the full-length spike protein of SARS-CoV-2 and Huh7 cell [12] . Lentiviral pseudotype bearing the truncated spike protein of SARS-C.....
Document: Recently, Michael Letko et al. used VSVdG-luc bearing SARS-spike chimeras to study the cell entry and receptor usage for SARS-CoV-2 and other lineage B betacoronaviruses [13] . Jianhui Nie et al. have successfully constructed a pseudovirus neutralization assay for SARS-CoV-2, which consist of pseudotyped VSV bearing the full-length spike protein of SARS-CoV-2 and Huh7 cell [12] . Lentiviral pseudotype bearing the truncated spike protein of SARS-CoV-2 was also constructed and used to study the virus entry and its immune cross-reactivity with SARS-CoV [6] . Noteworthy, the correlation between pseudovirus system and live . CC-BY-NC-ND 4.0 International license author/funder. It is made available under a The copyright holder for this preprint (which was not peer-reviewed) is the . https://doi.org/10.1101/2020.04.08.026948 doi: bioRxiv preprint virus system hasn't been verified. And the virus package and infection efficiency is also one of the limiting factors for high-throughput in vitro neutralization assay.
