CD20 (B Cell) [L26]
Description CD20 is a transmembrane phosphprotein which functions as a calcium-permeable cation channel involved in B cell activation, proliferation and differentiation. It is expressed on both normal and malignant B cells. The expression of CD20 is observed in all mature B lymphocytes but lost in terminal differentiated plasma cells. CD20 is one of the most important markers for B cell. It labels almost all mature B cell lymphoma, half of lymphoblastic lymphoma/leukemia and Reed-Sternberg cells in Hodgkin's disease. It has also been used to monitor down regulation of CD20 in patient treated with Rituximab for B cell lymphoma.

CD205/LY75/gp200 [SPM487]
Description CD205, also named DEC-205, belongs to the macrophage mannose receptor family of C-type lectin endocytic receptors. CD205 is predominantly expressed by the thymic cortical epithelium and by dendritic cells (DC), but can also be detected at low levels in T and B lymphocytes and several other epithelial cell types. CD205 is a novel thymic epithelial marker that is important for the positive selection process of thymocytes. It is a sensitive and specific marker for thymoma, while the sensitivity to thymic carcinoma is lower than CD5 and CD117.

CD22 [BLCAM/1795]
Description CD22 is a type 1 integral membrane glycoprotein with molecular weight of 130 to 140kD. It is expressed in both the cytoplasm and cell membrane of B lymphocytes. CD22 antigen appears early in B cell lymphocyte differentiation at approximately the same stage as the CD19 antigen. Unlike other B cell markers, CD22 membrane expression is limited to the late differentiation stages comprised between mature B cells (CD22+) and plasma cells (CD22-). CD22 is also strongly expressed in hairy cell leukemia. There are two different isoforms of CD22. It exists predominantly as a monomer of the beta isoform but can also be found as a heterodimer composed of the beta isoform and a second, shorter isoform (CD22 alpha).

CD23 [HD50]
Description CD23 antigen is a 45-60 kDa membrane glycoprotein identified as a low affinity receptor for IgE production as well as a receptor for lymphocyte growth factor. CD23 is found in some mature B-cell lymphomas and in Reed-Sternberg cells in Hodgkin disease.1 Follicular dendritic cells and some activated B-cells within germinal centers express CD23 in high density and mantle zone B-cells are stained weakly.2 The majority of chronic lymphocytic leukemias/small lymphocytic lymphomas are CD23 positive, whereas mantle cell lymphomas are generally negative, so this marker is useful when applied with other markers to separate the small cell lymphomas.2 Precursor B and T lymphomas, myeloid neoplasms, and mature T-cell lymphomas are CD23 negative and other small cell lymphomas are occasionally positive.3 CD23 is also positive on activated mature B-cells expressing IgM or IgD, monocytes/macrophages, follicular dendritic cells, T-cell subsets, eosinophils, Langerhans cells and small lymphocytic lym Host Mouse Application Flow cytometry (FC), Immunocytochemistry (ICC),Immunofluorescence (IF), Immunohistochemistry (IHC), Immunoprecipitation (IP) Reactivity Human -

CD235a/Glycophorin A [GYPA/280]
Description CD235a or Glycophorin A is the major intrinsic membrane protein of the erythrocyte. The N-terminal glycosylated segment, which lies outside the erythrocyte membrane, has MN blood group receptors. Appears to be important for the function of SLC4A1 and is required for high activity of SLC4A1. May be involved in translocation of SLC4A1 to the plasma membrane. Is a receptor for influenza virus. Is a receptor for Plasmodium falciparum erythrocyte-binding antigen 175 (EBA-175); binding of EBA-175 is dependent on sialic acid residues of the O-linked glycans. Appears to be a receptor for Hepatitis A virus (HAV). Strongly labels normal erythroid cells at all stages of differentiation from the erythroblast to the mature red cell and does not react with glycophorin B.

CD236/Glycophorin C [Ret40f]
Description Glycophorin C (GYPC or CD236) is an integral membrane glycoprotein. It is a minor species carried by human erythrocytes, but plays an important role in regulating the mechanical stability of red cells. A number of glycophorin C mutations have been described. The Gerbich and Yus phenotypes are due to deletion of exon 3 and 2, respectively. The Webb and Duch antigens, also known as glycophorin D, result from single point mutations of the glycophorin C gene. The glycophorin C protein has very little homology with glycophorins A and B. Alternate splicing results in multiple transcript variants. This protein is a minor sialoglycoprotein in human erythrocyte membranes. The blood group Gerbich antigens and receptors for Plasmodium falciparum merozoites are most likely located within the extracellular domain. Glycophorin-C plays an important role in regulating the stability of red cells. (Shipping Cost: €200.00) Host Mouse Application Immunohistochemistry (IHC) Reactivity Human
