Method and agent for detecting antibodies against human and animal retroviruses, especially T-lymphotropic viruses

摘要

Described are a method and means for the detection of antibodies against human and animal retroviruses, and more specifically T-lymphotropic viruses, by allowing a sample to be investigated to react with a human or ani­mal cell line infected with said viruses and subsequent­ly labelling by means of a second antibody directed against human antibodies bearing a marker. A cell line is used only part of the cells of which after the in­fection expresses viral antigens. The negatively-reac­ting cells are used as internal standard.
