The complement-fixing antigens present in tissue cultures infected with varicella-zoster virus were separated into four components. There were (i) a cell-free soluble antigen, (ii) a cell-associated soluble antigen, (iii) a cell membrane-associated antigen, and (iv) a virion antigen. All four antigens were reactive with sera from patients with varicella or zoster, and about 90% of the total complement-fixing activity was found to be nonvirion associated.
