The murine coronavirus surface glycoprotein gene was expressed as a fusion protein in bacteria, and the expressed protein was used to generate S protein-specific monoclonal antibodies (MAbs). Three of the MAbs, 11F, 30B, and 10G, were able to neutralize virus infectivity, and two of them, 11F and 10G, were able to block virus-induced, cell-to-cell fusion. The binding sites of the 11F, 30B, and ...
Human monoclonal antibodies (MAbs) were selected from semisynthetic antibody phage display libraries by using whole irradiated severe acute respiratory syndrome (SARS) coronavirus (CoV) virions as target. We identified eight human MAbs binding to virus and infected cells, six of which could be mapped to two SARS-CoV structural proteins: the nucleocapsid (N) and spike (S) proteins. Two MAbs reac...
Endogenous avian leukosis virus (ALVE) and the ALVE receptor (TVB*S1) status of six commercial chicken lines supplying specific-pathogen-free eggs were analyzed. All commercial chicken lines are certified free of the avian leukosis virus (ALV) by screening for expression of the p27 protein using the standard enzyme-linked immunosorbent assay. The commercial chicken lines A, E, and F contained r...
To investigate whether the human pro alpha 1(I) collagen chain could form an in vivo functional interspecies heterotrimer with the mouse pro alpha 2(I) collagen chain, we introduced the human COL1A1 gene into Mov13 mice which have a functional deletion of the endogenous COL1A1 gene. Transgenic mouse strains (HucI and HucII) carrying the human COL1A1 gene were first generated by microinjecting t...
A panel of murine hepatitis virus (MHV) surface (S) glycoprotein-specific monoclonal antibodies (MAbs), which recognize either continuous or discontinuous epitopes, were tested in competitive binding assays. The results indicate that the binding site of MAb 30B amino acids 395 to 406 in the amino-terminal S1 subunit, is involved in the discontinuous epitope designated antigenic site A. This sit...
The utilization of predicted splice donor and acceptor sites in generating equine infectious anemia virus (EIAV) transcripts in fetal donkey dermal cells (FDD) was examined. A single splice donor site identified immediately upstream of the gag coding region joins the viral leader sequence to all downstream exons of spliced EIAV transcripts. The predominant 3.5-kb transcript synthesized in EIAV-...
