Humans cannot make antibodies to viruses related to murine leukemia viruses unless they have been exposed to virus proteins.

At present, almost all of the predicted virus proteins have no known function.

Chiron has inserted the genes controlling production of some of he virus' proteins into yeast.

The mechanism of how the virus protein induces viperin against itself is still not clear.

If the blood contains HIV antibodies, they will stick to the virus proteins on the beads, which change color.

He shared a 1946 Nobel Prize for discovering methods of producing pure enzymes and virus proteins.

With a traditional vaccine, an artificial virus protein, or antigen, acts as a stimulus for antibody production.

But with a DNA vaccine, the virus protein is made in the cell rather than in the laboratory.

The hope is that these peptides might compete with the virus proteins for binding to the receptor molecules.

It is important to emphasize that these targets are not virus proteins, but host-cell proteins.
