Abstract
Precipitin antigen was prepared from cultures infected with V-Z virus. Five separate antigens were identified. Reactions with radiolabeled antigen were detected by autoradiography. Partial purification of antigens could be accomplished in a discontinuous sucrose gradient, yet too little antigen was recovered from DEAE to make this a practicable purification method. Most of the antigenic activity was eluted from G-200 Sephadex. Antigens were identified by their degree of chemical stability. The
antigen was the only one which was stable at pH 3. The
antigen was destroyed by CsCl or DOC. DOC released the
, and
antigens from the infectious viral particle.
