Radioimmunoassay for herpes simplex virus.

Radioimmunoassay has been used for time in the detection of the Australia Antigen. In this experiment, radioimmunoassay with Iodine-125 (125I) permitted rapid detection of the presence of herpes simplex virus, type I, in vitro. This is a convenient technique for the detection of virus, which now requires laborious methods involving observation for the cytopathic effect of virus upon cultured cells.
