Patent number: 4886743Abstract: This invention provides a reagent capable of binding to T cells and having specificity for a unique sequence within the variable region of the .beta. chain of the T cell receptor, the presence of increased number of T cells carrying the unique sequence relative to the number of T cells carrying the sequence present in a normal subject being associated with a specific disease. Specific diseases such as human cancers, e.g. lymphomas; autoimmune diseases, e.g. rheumatoid arthritis; Alzheimer's disease; infectious diseases, e.g. those caused by bacteria, yeast or parasite; or allergies, may be diagnosed as follows. A suitable sample containing T cells is obtained from a subject. The sample is contacted under appropriate conditions with such a reagent.
