Identifies EBV LMP-1 (latent membrane protein-1). EBV-LMP is 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. LMP-1 is a much less sensitive marker of EBV infection than EBER1 mRNA; the latter is detected by in situ hybridization.
