Abstract
Biological effects of agents for diagnostic or therapeutic use are evaluated by administration of the agents to transgenic animals which are transformed with heterologous DNA and which are immune tolerant to the expression product of the heterologous DNA. In a further embodiment, preparations that are immunogenic in the transgenic animal model are purified by reverse immunoaffinity chromatography on antibody obtained from responding transgenic animals.
