The PO3.1 monoclonal antibody specifically reacts with CD86, also known as B7-2, a surface 80 kDa receptor and member of the B7 family. CD86 is a costimulatory molecule, expressed on B and T cells, dendritic cells, astrocytes, macrophages, Langerhans cells, and at a low level in newly explanted B and T lymphocytes. CD86 expression on B lymphocytes is upregulated by B-Cell Receptor complex, CD40 and certain cytokine receptors. CD80 (B7-1) and CD 86 (B7-2) are receptors for CD28 and CTLA-4, on the surface of T lymphocytes, enhancing the interactions between B and T cells.

The 30-H12 monoclonal antibody specifically binds to MouseCD90.2, an alloantigen known as Thy-1.2, expressed on thymocytes, mature T cells, epithelial cells, neurons, hematopoietic stem cells, and fibroblasts. CD90 is a membrane glycoprotein that regulates the adhesion and signal transduction in T lymphocytes, and the adhesion of thymocytes to thymic stroma. The interaction between 30-H12 and the antibody to the CD3/TCR complex upregulates thymocytes signal transduction and apoptosis and downregulates mature T cell proliferation. The 30-H12 antibody seems to be unable to cross-link with CD90.1.

The 2.43 monoclonal antibody specifically reacts with mouse CD8 antigen. CD8a (the alpha chains) form heterodimers with CD8b (the beta chains) or homodimers (alpha-alpha), which occur as receptors on the surface of the majority of thymocytes. A subpopulation of mature T lymphocytes expresses the CD8 alpha beta (alpha beta TCR T cells), and a subpopulation of intestinal intraepithelial lymphocytes and dendritic cells express CD8a without CD8b. CD8 interacts with the mouse major histocompatibility complex class I (MHC class I) molecules on antigen-presenting cells or epithelial cells.

The 1A8 monoclonal antibody specifically reacts with the 21-25 kDa glycophosphatidylinositol-anchored protein known as Ly-6G, expressed by the granulocytes from the bone marrow and periphery neutrophils. Ly-6G and Ly-6C form the Granulocyte Receptor-1 antigen (GR-1). The binding of the 1A8 antibody to the Ly-6G can be blocked by another antibody, RB6-8C5, which also recognizes Ly-6C. While 1A8 is specific for only Ly-6G, RB6-8C5 also binds to Ly-6C.

The 188 monoclonal antibody binds to mouse B7-H4, a newly discovered member of the B7 family involved with the negative regulation of T cell immunity. B7-H4 is a type I membrane glycoprotein also known as B7S1, B7X, and VCTN1. Its role in tumor progression may be to protect precancerous cells from the surveillance of the immune system. Further studies are being conducted to determine the exact B7-H4 ligand. It is reported that the H74 antibody binds to mouse B7-H4 transfected cells and not spleen cells.

The ACK2 monoclonal antibody specifically reacts with mouse CD117 (c-Kit receptor), a 145 kDa transmembrane tyrosine-kinase receptor encoded by the Kit gene. The c-Kit receptor, also known as stem cell factor receptor, is expressed on hematopoietic progenitor cells in adult bone marrow, in progenitors of erythroid and myeloid lineages, and precursors of B and T cells. CD117 enhances the proliferation and the differentiation of the hematopoietic progenitor cells and seems to enhance the development of T cells, as the c-Kit receptor and its ligand are expressed by the thymus.

The Psel.KO2.3 monoclonal antibody specifically reacts with mouse CD62P (P-Selectin), a 140 kDA type I transmembrane glycoprotein also known as granule membrane protein 140 (GMP-140). Upon activation it is quickly transported to the plasma membrane from the alpha-granules of platelets and WEibel-Palade bodies of endothelial cells. It is essential to the functions of cell adhesion during inflammatory reactions and in the interaction of platelets with monocytes and neutrophils. The Psel.KO2.3 antibody does not block adhesion and binds to an epitope common to several species including mouse, human, and rat.

The Mar-1 monoclonal antibody binds to the Fc ε Receptor I α subunit (FceR1a), which is a transmembrane glycoprotein from the immunoglobulin superfamily. FceR1a lacks signal-transducing ability and is expressed by mast and basophil cells.The Fc ε Receptor I α subunit is upregulated by IgE and forms a tetramer with a beta subunit and two gamma subunits, which have ITAM (immunoreceptor tyrosine-based activation motifs). The complex formed by the four subunits has very important roles in the IgE-facilitated allergic reactions.

The MP6-XT22 monoclonal antibody specifically reacts with mouse tumor necrosis factor alpha (TNF-alpha), a 156 amino pro-inflammatory cytokine. It is secreted by various cells including adipocytes, activated monocytes, macrophages, B cells, T cells and fibroblasts. NF-α is cytotoxic to a wide variety of tumor cells and is an essential factor in mediating the immune response against bacterial infections. TNF-α also plays a role in the induction of septic shock, auto immune diseases, rheumatoid arthritis, inflammation, and diabetes. The MP6-XT22 is reported to neutralize the bioactivity of natural or recombinant TNF-alpha and is useful for intracellular immunofluorescent staining.

The N418 monoclonal antibody specifically reacts with the integrin αx chain of the mouse CD11c, which is expressed on dendritic cells, CD4-/CD8+ intestinal intraepithelial lymphocytes (IEL) and some activated T lymphocytes. Low levels of CD11c were detected on mouse splenic natural killer cells and on the monocyte/macrophage lineage cells.CD11c expression is upregulated on IEL and T lymphocytes after activation. It binds to CD54, fibrinogen and iC3b and influences the leukocyte adhesive interactions. The N418 antibody binds to CD11c on splenic dendritic cells of the mouse in the T-dependent areas. It also contributes to the binding of iC3b.

The PC61.5 antibody specifically reacts with mouse CD25, the 55 kDa low-affinity Interleukin-2 Receptor α chain (IL-2R α), expressed on early progenitors of T and B lineage, and on B and T cells. Together with CD122 (IL-2 Receptor β) and CD 132 (IL-2 Receptor γc, the common gamma chain), CD25 forms high-affinity receptor complexes for IL-2. Resting B and T cells and natural killer cells do not express IL-2Rα. Cd25 is also expressed on the dendritic cells, and it enhances lymphocyte differentiation and activation.The PC61.5 antibody blocks the binding of IL-2 to both high-affinity and low-affinity receptors.

The 30-F11 monoclonal antibody specifically reacts with all isoforms of CD45 and also with the alloantigens CD45.1 and CD45.2 (LCA). CD45 is a transmembrane glycoprotein, expressed by all the hematopoietic cells, except for platelets and mature erythrocytes, which distinguishes the leukocytes from the non-hematopoietic cells. The CD45 molecule is a member of the Protein Tyrosine Phosphatase (PTP) family, because its intracellular region contains two PTP domains. The extracellular region’s variability is caused by different levels of glycosylation, and the splicing of the 4, 5, and 6 exons.The isoforms found in the mouse strains depend on the activation state, maturation stage and cell type, and are very important in B and T lymphocytes antigen receptor signal transduction.
