we describe ways of raising human hybridomas that produce rf antibodies in rheumatoid arthritis ( ra ) in order to elucidate how these antibodies differ from the rf antibodies that are part of the normal immune response in man and animals , and from those in diseases other than ra , e.g . in m-components seen in mixed cryoglobulinaemia and in waldenstrom 's macroglobulinaemia .
