Epstein-Barr-Virus-Positive B-Cell Lymphoma of Recipient Origin Despite of the Elimination of Clonally EBV-Infected T Cells by Allogeneic Stem Cell Transplantation in a Patient with Chronic Active EBV Infection

Figure 1

Infection status of EBV was monoclonal. DNA from the patient’s peripheral blood mononuclear cells was digested by EcoRI, and southern blot hybridization was performed with EBV BamHI W probe. An arrow points at the monoclonal bands. Asterisk shows the nonspecific band. N: normal control; P: patient; P.C.: positive control (Raji cells).
