Radioimmunoassay of the group-specific antigen in detection of avian leukosis virus infection.

The major group-specific antigen (gs-a) of avian leukoviruses was detected by radioimmunoassay in extracellular medium of all embryonic cultures prepared from infected chickens. Embryos of birds not carrying an avian ]eukosis virus infection and of chickens from a leukosis-free flock could thus clearly be distinguished from infected ones. Release of group-specific antigen into the extracellular...

Ultrastructure of the surfaces of cells infected with avian leukosis-sarcoma viruses.

When stained with ruthenium red (RR), chick embryo cells infected with various strains of Rous sarcoma virus (RSV) and with avian leukosis viruses RAV-1 and RAV-3 showed an increase in the layer of acid mucopolysaccharides (AMPS) at their surfaces as compared with uninfected cells. This increase was most prominent in cells infected with the Fujinami strain of RSV. The layer was resistant to dig...

Radioimmunoassay for the envelope glycoprotein of subgroup E avian leukosis-sarcoma viruses.

In the absence of infectious subgroup E avian leukosis-sarcoma (ALS) viruses, some chicken embryo cells contain in their cell membrane the envelope glycoprotein of subgroup E viruses (gpE) (Hanafusa et al. 1973). The partial expression of subgroup E virus was first recognized as chick-cell-associated helper factor (chfl, which provided the helper function for the envelope-defective Bryan high-t...
