✦ Synopsis
Abstract
Immunofluorescence absorption methods are described which permit quantitative estimation and differentiation of Epstein‐Barr virus (EBV)‐associated antigens (virus capsid antigen, VCA, early antigen, EA and EBV‐determined nuclear antigen, EBNA) in cell extracts. EBNA was present in all cell lines (producer and non‐producer) which carried the EBV‐genome, while VCA and EA were present in producer lines only. All the antigens were absent from a lymphoid cell line (MOLT‐4) which lacked the EBV‐genome, as well as from leukemia cells from peripheral blood. The techniques demonstrated antigenic identity of the various antigens when prepared from different cell lines.
