Abstract

We established sixteen mouse monoclonal antibodies (MAbs) reactive to Chuzan virus K-47 strain using P3-X63-Ag8-U1 cells as fusion partners. Among them, CG53/2/4 recognized a 100K structural protein of the virus. This 100K antigen is a glycoprotein which is essential for the infection of Chuzan virus. The other anti-Chuzan virus MAbs reacted with a 41K antigen of the virus. Especially CGI/1 showed the highest reactivity to the virus. Forward step sandwich assay using CG1/1 and biotinylated CG53/2/4 could detect Chuzan virus at 10 TCID50/ml. Furthermore we established fourteen MAbs reactive to bovine ephemeral fever virus (BEFV) YHL strain. Among them, YM4/9 reacted specifically with a 43K antigen of BEFV, corresponding to the matrix protein 1. The other MAbs reacted not only with the 43K antigen, but also with unknown 23K and 21K antigens. By a simultaneous two-site method using YM4/9 and YG3/4, it was possible to detect 104 . 10TCID50/m1 of BEFV in the presence of bovine serum. Therefore, these MAbs can eventually predict the virus infection of cattle before sideration.
