Biochemically silent posttransfusion non-A, non-B hepatitis interferes with superinfection by hepatitis A virus.

abstract：:Virions of maize rayado fino virus (MRFV) were purified and two major capsid proteins (ca. Mr 29,000 and 22,000) were resolved by SDS-PAGE. When the two major capsid proteins were isolated from gels and compared by one-dimensional peptide mapping after digestion with Staphylococcus aureus V-8 protease, indistinguishab...
