- The infected 293 T cells were transfected with the plasmid encoding HA-tagged hA3B plasmids (293 T/XMRV/hA3B and 239 T/MX/hA3B) or control plasmids (293 T/XMRV/pcDNA3 and 293 T/MX/pcDNA3). HeLa cells were infected with XMRV released from the viral producing cells described above. *The infectious units (IU) were measured from the number of infectious centers that was normalized by the amount of Capsid in viruses and IU per ml was shown. **The relative infectivity to the HeLa cells infected with the virus released from 293 T/XMRV/pcDNA cells was shown.
