Methods
Direct spectrophotometric assay. This was carried out using p-dimethylaminomethylbenzylamine as substrate as previously described (1,111.
Indirect spectrophotometric assays. These were carried out as described (2-4,12). A Cary 118C UV-VIS spectrophotometer was used throughout this study.
Enzyme puriJication. Human placental diamine oxidase was prepared as previously described (I 1) to a final specific activity of 1.3 U .mg-I. Highly 676

Most of the methods currently available for the determination of RNase activity are dependent on the measurement of acid-soluble products released 'by hydrolysis of RNA. The major advantages of these methods are that they are sensitive, reproducible, and convenient for large numbers of samples (l-3)
## Abstract A useful method for the detection and assay of EpsteinβBarr virus (EBV)βrelated soluble antigen has been developed by the application of the indirect single radial immunodiffusion technique which is frequently used for quantitative measurements of immunoglobulins and other soluble prote
