## Abstract The Epstein‐Barr virus nuclear antigen I (EBNA I) is the only latent EBV antigen consistently expressed in malignant tissues of the nasopharynx. A 20‐amino‐acid synthetic peptide, p107 contains a major epitope of EBNA I. We tested sera from 210 patients with nasopharyngeal carcinoma (NP

Abstract
Epstein‐Barr virus nuclear antigen (EBNA) preparations from three sources were tested with sera from normal individuals and patients with Hodgkin's disease, breast carcinoma, Burkitt's lymphoma, and American and Chinese nasopharyngeal carcinoma. Individual sera with discordant antibody patterns were noted in all groups. Sera from both NPC groups gave significantly higher anti‐EBNA titers on cell lines converted with P3HR‐1 or B95‐8 virus compared with anti‐EBNA titers on Raji cells. Anti‐EBNA titers of Chinese NPC sera showed no correlation among the three EBNA sources, while all other groups had highly correlated titers. Cross‐absorption experiments present evidence for more than one antigenic determinant on EBNA. These results suggest an additional parameter for distinguishing Chinese NPC from other EBV‐related disorders.

## Abstract Sera were collected at intervals of 3 to 8 months over a 4‐ to 5‐year period from more than 103 patients with nasopharyngeal carcinomas (NPC) and examined for their spectra and titers of antibodies to Epstein‐Barr virus (EBV)‐related antigens. They were titrated for IgG, IgA and IgM ant
## Abstract Fresh nasopharyngeal carcinoma (NPC) biopsies were treated in several ways to yield satisfactory cell preparations for detection of Epstein‐Barr virus (EBV)‐associated nuclear antigen (EBNA) by anti‐complement immunofluorescence tests. If the cells were well dispersed (trypsinization or
## Abstract Biopsy specimens from Alaskan Native patients with nasopharyngeal carcinoma (NPC) and from other patients seen on the otolaryngology service were tested for Epstein‐Barr virus‐specific DNA and nuclear antigen (EBNA). Serum samples from both groups were tested for various EBV‐related ant
Specific antibody responses against the 2 major subcomponents of EBNA, EBNAl and EBNAZ were evaluated, in order to study whether this serological study was beneficial compared to classical EBV serology. During this investigation, 491 sera, obtained from blood donors and patients with Burkitt's lymph
