General description

Anti-CD20 (pan B-cell) reacts with a membrane antigen that is present in B-cells as this epitope is acquired late in the pre-B-cell stage of maturation and remains on cells throughout most of the differentiation process, although it is lost at the plasma cell stage. This antibody recognizes Reed-Sternberg cells, predominant in classic Hodgkin′s disease, in approximately 20% of cases, and approximately half of lymphoblastic lymphoma/leukemias. Since no staining of histiocytes or plasma cells has been observed and CD20 has rarely been detected in T-cell malignancies, it is a dependable marker of B-cell lymphomas. Anti-CD20 does not cross-react with non-hematopoetic neoplasms.

Linkage

CD20 Positive Control Slides, Product No. 120S, are available for immunohistochemistry (formalin-fixed, paraffin-embedded sections).

Physical form

Solution in Tris Buffer, pH 7.3-7.7, with 1% BSA and <0.1% Sodium Azide

The American journal of pathology, 133(2), 211-217 (1988-11-01)
Immunoreactivity for L26, a highly effective pan B cell marker that can be detected in paraffin sections, was evaluated in 72 cases of Hodgkin's disease of various histologic types. In all cases of nodular lymphocyte predominance type of Hodgkin's disease

Histopathology, 24(6), 511-515 (1994-06-01)
Recent evidence indicates that membrane-bound immunoglobulin on B lymphocytes is associated with a molecule which comprises the products of the mb-1 and B29 genes. This molecule is a highly specific marker for B-cells, presumably because of its central functional role

Laboratory investigation; a journal of technical methods and pathology, 52(5), 497-504 (1985-05-01)
Monoclonal antibodies (MoAbs) to B cell- and T cell-specific antigens uniformly have been restricted in their use to cell suspension or frozen section techniques because the antigens that they identify are either masked or lost in the fixation or paraffin-embedding
A L Epstein et al.
Journal of immunology (Baltimore, Md. : 1950), 133(2), 1028-1036 (1984-08-01)
Two monoclonal antibodies (LN-1, LN-2) reactive with B lymphocytes in B5 formalin-fixed, paraffin-embedded tissue sections have been produced by utilizing cell extracts from pokeweed mitogen-stimulated peripheral blood lymphocytes and diffuse histiocytic lymphoma SU-DHL-4 cells, respectively. Both monoclonal antibodies were initially
