Study on expression of Epstein-Barr virus nuclear antigens in various infected states of cells

y microspectrophotometer quantitation(the expressing level of three kinds of EBNAs were detected with anti￣EBNA antitheies purified from human serum by Western blotting method,The resultsshowed that EBNA-1 expressed greatly in latently infected Rajicell.When they were got into aborted-ly infected state treated with croton oil and n-Butyrate,the ex pression level of EBNA-1 decreased andthat of EBAN-2 increased,B_(95-8) cell had a similar variation,It suggeets that the activation of EB virusmight associated with the expression level of EBNAs.
