However, using MHV or SDAV-infected cells as the source of antigen, there was a significant difference in antibody titers to the homologous virus detected using the immunoenzyme technique. Using the I F A procedure and MHV-, SDAV-, or PRC-infected cells as a source of antigen and sera from rats exposed to S D A virus, antibody titers to all three antigens were similar (Table 1 ). ./cache/cord-343256-n593kh7u.txt ./txt/cord-343256-n593kh7u.txt
