Description: The lymphocyte Fcγ receptors recognize the Fc portion of IgG, presented either as immune complexes or as free antibody. The different classes of receptors are distinct because of varying size, tissue distribution and affinity for IgGs. The Fc type II receptor is expressed on a wide variety of cells including B cells, hematopoietic cells, monocyte/macrophages, neutrophils, platelets, Langerhans cells, eosinophils, basophils, trophoblasts, and endothelial cells of the placenta. The Fcγ type III receptors are higher affinity than the type II and are expressed on macrophages, NK cells and neutrophils. Both types of receptors can be expressed on the same cell and in varying ratios. The receptors are constitutively expressed, although cytokines and lymphokines can modulate their expression. Besides identifying FcγR+ cells, monoclonal antibodies to the FcγII/III receptor have been used to block Fc receptor binding of IgG, Fc-mediated signal transduction and effector functions, clearance of immune complexes and to attenuate infection by organisms dependent on FcγR for parasitic invasion. The monoclonal antibody 93 recognizes a conformational epitope formed by FcγII and FcγIII receptors.

Description: CD4 is a type I transmembrane glycoprotein expressed on most thymocytes and the helper/inducer subpopulation of mature T lymphocytes of all mouse strains tested. CD4 has also been detected at low density on pluripotent hematopoietic stem cells, bone marrow myeloid precursors, and intrathymic lymphoid precursors. The CD4 antigen functions as a co-receptor, interacting with class II major histocompatability complex (MHC) molecules in the recognition of foreign antigens by T cells. In vivo and in vitro treatment with the GK1.5 monoclonal antibody effectively depletes CD4+ cells. GK1.5 also blocks helper T cell responses to MHC class II antigens, including cytolysis, proliferation, allogeneic B cell help, and release of lymphokines.

Description: BP-1, also known as Ly-51 and 6C3 antigen, is a type II homodimeric transmembrane glycoprotein formed by two disulfide-linked chains of 140 kDa. Originally identified on the surface of pre-B cell lymphomas the cDNA encoding BP-1 has been cloned and found to represent aminopeptidase A. It is expressed at high levels on bone marrow stromal cell lines which support in vitro B lymphopoiesis and on a wide variety of mouse tissues known to possess aminopeptidase activity. Subsets of normal bone marrow pre-B and B cells express low levels of BP-1 which is rapidly upregulated on pre-B cells in the presence of IL-7. The BP-1 marker is commonly used to identify B cells in different stages of development.

Description: The TCRγδ heterodimer of the CD3/T cell receptor complex is clonotypic and consists of Ig-like variable and constant domains. It is expressed during thymopoiesis and on the small subpopulation of γδ TCR-expressing T lymphocytes in the periphery. The majority of T cells present in some epithelial tissues are γδ+ and have limited receptor diversity. The TCRγδ heterodimer recognizes peptide antigen bound to MHC antigens and subsequent signal transduction mediated by the invariant chains leads to T cell activation. The monoclonal antibody UC7-13D5 is specific for the γδ heterodimer and plate-bound UC7-13D5 activates γδ TCR-bearing cells. This antibody does not react with αβ TCR-expressing T cells.

Description: CD8 is a 33 kDa transmembrane glycoprotein expressed as either a CD8αα homodimer or CD8αβ heterodimer. It is expressed on the “cytotoxic/suppressor” subpopulation of peripheral T cells. CD8 functions primarily as a coreceptor with MHC class I-restricted TCR’s in antigen recognition.

Description: CD57 represents a 110 kDa oligosaccharide antigenic determinant present on a variety of polypeptides, lipids, and chondroitan sulfate proteoglycans. It is expressed on 7-35% of normal peripheral blood lymphocytes, including subsets of NK cells and CD8+ T lymphocytes. The carbohydrate is expressed on various cell adhesion molecules in the nervous system and is suggested to play a role in cell–cell and cell–substrate interactions.

Description: CD43, a member of the sialomucin family of cell surface receptors, is a 95-135 kDa type I transmembrane glycoprotein whose variability in molecular weight is dependent upon the nature of the extracellular O-glycans. It is the major sialoglycoprotein on thymocytes, T cells, and neutrophils. It is also present on activated B cells, plasma cells, NK cells, granulocytes, monocytes, macrophages, platelets, and bone marrow hematopoietic stem cells. CD43, which binds to ICAM-1 (CD54), appears to function as an anti-adhesion molecule, inhibiting T cell interactions including T cell killing, and by increasing the threshold for T cell activation.

Description: The CD45 antigen is an essential regulator of leukocyte activation and development and is now known to be a protein tyrosine phosphatase, e.g., CD45 is able to dephosporylate the Src family of protein kinases. This activity is known to be required for signal transduction induced by T and B cell antigen receptor engagement, cytokine signaling, and Fc receptor stimulation. The functional state of CD45 also has a pronounced effect on lymphocyte development. CD45 exists in multiple forms, such as the restricted variants (CD45R; see companion products 1660, 1665, 1675, 1685 and 1820) and as allelic forms CD45.1 (Ly-5.1) and CD45.2 (Ly-5.2). The specificity of antibodies to CD45.1 and CD45.2 has been exploited in studies where resolution of donor and recipient cells is essential, such as in gene therapy or bone marrow transplantation. The monoclonal antibody 104 recognizes CD45 (leukocyte common antigen) on all leukocytes of mouse strains expressing the CD45.2 allotype (e.g., A, AKR, BALB/c, CBA/Ca, CBA/J, C3H/He, C57BL, C57BR, C57L, C58, DBA/1, DBA/2, NZB, SWR, 129).

Description: CD104 represents the integrin β4 subunit that associates non-covalently with integrin α6 (CD49f) to form the α6β4 integrin heterodimer. The α6β4 complex is expressed on the basal surface of a variety of epithelial cell types particularly on stratified squamous epithelia. It is also found in peripheral nerves, in certain subsets of endothelial cells, and on immature thymocytes. It also has been found to be associated with a number of malignant tissues. Hemidesmosomal α6β4 plays an important role in the adhesion of epithelial cells to basement membranes via interactions with laminin and/or kalinin anchoring filaments. It is not known if the monoclonal antibody 346-11A can block this adhesion.
