Abstract
WE have characterised1 type C virions which are released spontaneously from a diploid strain of human embryonic fibroblasts. These ‘HEL-12 virions’ have structural and biochemical properties of known RNA tumour viruses and are antigenically related to subhuman primate type C viruses. Immunological analyses have so far excluded cross reactivity between HEL-12 virions and avian (ASV), murine MuSV, or feline RNA sarcoma or leukaemia viruses.
