Biologie, serologie et biochimie de virus leucemogenes derives d'une tumeur radioinduite de la souris c57bl.

: Two distinct rat propagates of a radiation leukemia virus (RadLV-Rs) from the C57BL mouse respectively induced characteristic leukemogenic effects. These were found to be related with the infection titers of the isolates, but not with either their antigenic specificities or their viral and proviral genome sequences.
