Antibodies against the chemically synthesized genome-linked protein of poliovirus react with native virus-specific proteins.
The genome-linked protein (VPg) of poliovirus has been chemically synthesized, coupled to bovine serum albumin carrier and injected into rabbits. An antibody response was elicited not only by the full-length synthetic VPg peptide, but also by a synthetic 14-amino acid carboxy-terminal peptide. All antisera reacted with virus-specific proteins from HeLa cells infected with poliovirus. Three of these proteins have previously been implicated by others as precursors of VPg. No free cytoplasmic VPg could be detected, and the antibodies did not react with radiolabeled proteins from uninfected cells.
