Abstract
N-tropic Friend leukaemia virus (FLV) was serially passaged in a B-type C57BL/6 mouse cell line, YH-7. After a single passage, the infectious efficiency of FLV in the restrictive YH-7 cells was significantly increased. This adapted character of FLV could be reversed by a single passage in permissive N-type MLg cells. The true host range conversion from N to NB was accomplished after eleven to twelve passages in YH-7 cells. In contrast, the host range conversion of N-tropic murine sarcoma pseudotype, MuSV(FLV), took place after two passages.
