Abstract:
:The Epstein-Barr virus (EBV)-induced membrane antigen (MA) was successfully solubilized from the membranes of viable EBV-infected Raji cells by treatment with papain (5 to 6 U per 1 X 10(7) to 2 X 10(7) cells). The loss of MA from viable cells was monitored by membrane immunofluorescence and antibody-dependent cellular cytotoxicity. Soluble MA was demonstrated in papain digests through inhibition of antibody-dependent cellular cytotoxicity and by inhibition of the binding of anti-MA antibodies to cells as detected by use of 125I-labeled staphylococcal protein A. Approximately 75% of the MA activity in the extracts was not sedimentable at 100,000 X g,, indicating that the majority of EBV MA activity that was released by this procedure was associated with small-molecular-weight material. Antiserum prepared from an owl monkey immunized with these papain extracts contained antibody to MA and neutralizing antibodies, but lacked detectable antibodies against viral capsid antigens and EBV-induced early antigens.
