Abstract
To test whether autoimmune hemolytic anemia in a patient with chronic lymphocytic leukemia was due to autoantibody production by the neoplastic clone, somatic cell hybrids were constructed between the patient''s leukemic cells and a mouse myeloma line. L chain-restricted human immunoglobulin was secreted by 4 of 11 of the established hybrid lines. No binding of this immunoglobulin to red cell surface antigens could be detected. The autoantibody in this patient apparently represented a concomitant reactive response and was not the product of the malignant clone of B [bone marrow derived] cells.
