the ability of normal non-t cells or non-t cells from patients with chronic lymphocytic leukemia ( cll ) to form rosettes with human red blood cells coated with spa ( spa-hrbc ) was strongly inhibited or abolished by incubation with f ( ab ' ) 2 fragments of antibodies against human immunoglobulin ( ig ) , whereas the incubation with f ( ab ' ) 2 fragments of antibodies against a non-ig cell surface antigen , such as beta 2-microglobulin , had no effect on the spa-rosetting of human lymphocytes .
