General description

Anti-CD20 (B-cell Pan) reacts with a membrane antigen that is present in B-cells. This antibody recognizes Reed-Sternberg cells, predominant in Hodgkin′s disease, in a minority of cases. Since no staining of histiocytes or plasma cells has been observed and CD20 has not been detected in T-cell malignancies, it is a very strong marker of B-cell lymphomas. Anti-CD20 does not cross-react with non-hematopoetic neoplasms.

Recent evidence has demonstrated that classical Hodgkin lymphoma (cHL) originates from mature germinal center B cells. However, only approximately 25% of cHLs express the classical B-cell marker CD20. There is very little, and controversial, information on the prognostic significance of

The use of monoclonal and polyclonal antibodies for the immunophenotyping of non-Hodgkin's lymphomas in paraffin-embedded tissue has been limited by the fact that most antigens on lymphoid cells are denatured by histologic fixation, dehydration, and embedment. In this article the

Two distinct antigen systems (L26 and L27) specifically expressed in human B lymphocytes were identified using TB2-2B3 (2B3) and T3-5B3 (5B3) monoclonal antibodies, respectively. Whereas L26 antigen defined by 2B3 were rarely expressed on the surface of B cells but
