📄 Comparison of six different murine coronavirus jhm variants by monoclonal antibodies against the e2 glycoprotein

We have examined six different JHMV variants, sp-4 (recloned wt JHMV), cl-2, CNSV, DL, DS, and JHM-X, in terms of the sizes of the mRNA3 and E2 glycoprotein as well as their reactivity to a panel of monoclonal antibodies to the E2 glycoprotein. Two of these variants, sp-4 and JHM-X, were found to have smaller mRNA3 and E2 glycoprotein species compared with those of the other four variants. In addition, sp-4 and JHM-X were distinguished from the other four variants by their inability to bind to monoclonal antibodies recognizing two antigenic domains of the E2 molecule. Thus, six JHMV variants could clearly be divided into two groups with respect to the size and antigenicity of their E2 glycoproteins. © 1989.
