Its epitope is located in the cytoplasmic domain of CD20 and was, therefore, ascribed as CD20cy in the 5th Workshop. CD20 is a non-Ig differentiation antigen of B-cells and its expression is restricted to normal and neoplastic B-cells, being absent from all other leukocytes and tissues. CD20 is expressed by pre B-cells and persists during all stages of B-cell maturation but is lost upon terminal differentiation into plasma cells. This MAb can be used for immunophenotyping of leukemia and malignant cells, B lymphocyte detection in peripheral blood and B cell localization in tissues. It reacts with the majority of B-cells present in peripheral blood and lymphoid tissues and their derived lymphomas. In lymphoid tissue, germinal center blasts and B-immunoblasts are particularly reactive. It is a reliable antibody for ascribing a B-cell phenotype in known lymphoid tissues. Rarely, CD20-positive T-cell lymphomas have been reported. Reactivity has also been noted with Reed-Sternberg cells in cases of Hodgkin s disease, particularly of lymphocyte predominant type.<\/p>\n<div style=\"margin:18px 0 4px;padding:11px 14px;background:#fdf4f4;border:1px solid #e6bdbd;border-left:3px solid #c41e3a;border-radius:4px;font-size:13px;line-height:1.55;color:#3a3a3a;\"><strong style=\"color:#8a1524;\">For Research Use Only (RUO).<\/strong> This product is sold strictly for laboratory research use only. <strong>Not for human or veterinary consumption, therapeutic, or diagnostic use.<\/strong> Any pharmacological, therapeutic, cosmetic, or biological effects described above are provided as research context only and do not represent intended or approved uses of this product.<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Size: 50 \u00b5L This antibody recognizes a protein of 30-33 kDa, which is identified as CD20.
