mBaoJin-labeled pangolin coronavirus for evaluating population cross-neutralizing antibodies and the entry-inhibitory activity of cepharanthine
Replication-competent coronaviruses carrying fluorescent protein-tagged structural proteins remain scarce. Using the highly attenuated pangolin coronavirus GX_P2V(short_3UTR) as a backbone, we generated GX_P2V-mBJ-N, a recombinant coronavirus in which the bright green fluorescent protein mBaoJin is fused to the nucleocapsid (N) protein. The reporter virus is attenuated and genetically unstable in…
