To investigate if virus attachment, internalization, disassembly and infection occurs in the CHOSn-CD163 and PK15Sn-CD163 cells, CHOSn-CD163 clone IC5 and PK15Sn-CD163 clone IXH7 were inoculated with Marc-145 grown LV (moi 1), Marc-145 grown VR-2332 (moi 1) and macrophage grown LV (moi 1). Here, CD163 is linked to infection.
