Manipulation of one site or a component of it generally did not affect the reactions of the others, suggesting that they form independent structural features. The extent to which the inserted site expressed the antigenic properties of type 3 could be assessed by reaction with polyclonal or monoclonal antibodies, or by immunogenicity. Site 2 could be expressed on infectious virus and site 3 on heated non-infectious virus (C antigen), but not on the native virion. The results are consistent with the view that sites consisting of a continuous sequence of amino acids may be presented on chimeras, whereas more complex sites, such as site 4 or site 3 of the native virion, are transferred less readily from type 3 to type 1.", }
