  • a Data are averages of infections performed in duplicate. MAGI cells were infected with 102to 104 infectious virions, as determined by sMAGI assay. A value of 0 indicates that no cells were infected when cultured with a minimum of 104 infectious virions.

  • b RNA, virions associated with vRNA; TCIDsMAGI, titers of virus stocks with sMAGI indicator cells (infectious virions/ml).
