Abstract
Summary
An antigenic reactivity characteristic of the Forssman antigen was demonstrated on the surface of SV40 and polyoma transformed hamster cells and in hamster cells in tissue culture by the use of a heterologous antiserum and immunofluorescent techniques. No Forssman reactivity was detected with adenovirus 12 transformed hamster cells or with mouse cells transformed with SV40 or polyoma viruses. The SV40-specific surface antigen could not be demonstrated with these heterologous antisera. The possible relationship of these new antigenic determinants which appear following virus transformation to the surface components normally present was discussed.
