Identifies EBV latent membrane protein-1, a cell surface-associated protein encoded by the EBV genome and expressed by a subset of EBV-infected B-cells, more commonly in tonsils than in lymph nodes of EBV-infected individuals. This antibody reacts strongly with EBV-positive lymphoblastoid cell lines and EBV infected B-cell immunoblasts in infectious mononucleosis, and also reacts with some EBV-associated neoplasms, particularly EBV-associated Hodgkin lymphoma. It is a much less sensitive marker than EBER.
