title: A monoclonal antibody to the heavy chain of human IgM with a particular reaction pattern in human B-cell malignancies.
abstract: We produced a monoclonal antibody to the human mu-chain. Its specificity was proved by amino acid-sequence analysis of immunoabsorbent purified cell surface antigen. In binding studies an affinity constant (K-aff) of 5.7 X 10(9) M-1 was determined. When compared with a polyclonal anti-IgM antiserum it was found that this antibody may react with a determinant of the mu-chain differently exposed in clonal B-cell disorders rendering it to a reagent of particular diagnostic interest.
