title: Micro-radioimmunoassay for antibodies to Newcastle disease virus in the chicken.
abstract: An indirect micro-radioimmunoassay is described in which chicken anti-Newcastle disease virus antibody was detected, with radioactively labeled rabbit anti-chicken Fab, on virus-infected microcultures of chick embryo fibroblasts. Newcastle disease virus-infected microcultures were formalin fixed and stored at 4 degrees C for up to 4 months without affecting the sensitivity of the test. The micro-technique was found to be highly sensitive and specific assay of anti-viral antibody and may allow detection of immunoglobulin class of anti-Newcastle disease virus antibody.
