Summary
We produced a monoclonal antibody to the human μ-chain. Its specificity was proved by aminoacid-sequence analysis of immunoabsorbent purified cell surface antigen. In binding studies an affinity constant (K-aff) of 5.7×109 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 μ-chain differently exposed in clonal B-cell disorders rendering it to a reagent of particular diagnostic interest.
