Description: The FN50 monoclonal antibody specifically reacts with human CD69, the 27-33 kDA type II transmembrane protein also known as the very early activation antigen (VEA) or the activation inducer molecule (AIM). It is expressed as a disulfide-linked dimer on B cells, T cells, NK cells, platelets, eosinophils, and neutrophils. It increases in expression upon cell activation and seems to serve a role as a signaling receptor.

Description: The RPA-T4 monoclonal antibody specifically binds to the CD4 receptor for the human immunodeficiency virus (HIV). CD4 is a 59 kDa single-chain transmembrane glycoprotein that expressed on the surface of most of the thymocytes, T-helper cells, and in low levels on monocytes and macrophages. CD4 is a co-receptor in the antigen-induced T cell activation, together with the MHC class II. The RPA-T4 antibody is capable of blocking HIV binding and inhibiting syncytium formation, by binding to the D1 domain of the CD4 antigen. The OKT4 and the RPA-T4 monoclonal antibodies recognize different epitopes of CD4 and they do not exhibit cross-block binding.

Description: The C17.8 antibody specifically reacts with the p40 subunit of IL-12, as free monomer, as a homodimer, or as a part of the p70 dimer. C17.8 seems to neutralize the activity of mouse IL-12 and IL-23. IL-12 is the p70 heterodimer of p35 and p40, expressed by the macrophages, dendritic cells, and monocytes. The C17.8 antibody cross-reacts with IL-23, since IL-23 also contains one p40 subunit.

Description: The 2F1 monoclonal antibody is specific for the mouse Killer cell Lectin-like Receptor G1 (KLRG1), a homodimer consisting of two N-glycosylated subunits of 30-38 kDa, also known as MAFA (Mast cell Function-associated Antigen). The antigen contains a cytoplasmic motif similar to ITIM (the immunoreceptor tyrosine-based inhibitory motif). KLRG1 is a receptor for cadherin, a family of transmembrane glycoproteins that mediate cell adhesion, and a common marker of T cell senescence. The receptor is believed to play an important role in the innate and adaptive immune system through the regulation of leukocytes. It is expressed on lymphokine-activated killer (LAK) cells, adherent LAK (A-LAK) cells, a sub-set of natural killer (NK) cells, T cells. In NK cells, it inhibits cytokine production and cytotoxicity activity.The receptor expression was not detected on the mouse peritoneal mast cells, or bone marrow mast cells.

Description: 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.

Description: The 2A3 antibody was obtained by hybridization of MouseNS-1 myeloma cells with spleen cells harvested from BALB/c mice immunized with phytohemagglutinin-activated human T cells. The 2A3 antibody is a CD25 clone and used as an Isotype Control for rat IgG2a antibodies. BG Violet 450 conjugate is an alternative to the Pacific Blue, eFluor 450, or BD Horizon V450 dyes. It is excited by the violet (405 nm) laser, with a peak emission of 450nm.

Description: The 3.9 monoclonal antibody specifically binds to the human adhesion glycoprotein CD11c, a 150 kDA integrin α chain also known as integrin alpha X. It is expressed on macrophages, granulocytes, monocytes, dendritic cells, natural killer cells, and subsets of B and T lymphocytes. The CD11c/CD18 complex associates with the iC3b, fibrinogen and ICAM-1 and has an important function in leukocyte adhesion.

Description: 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.

Description: The 390 monoclonal antibody specifically reacts with mouse cd31, a 130-140 kDA type I transmembrane glycoprotein also known as platelet-endothelial cell adhesion molecule-1 (PECAM-1). CD31 is reported to bind to CD38 and is expressed on platelets, monocytes, granulocytes, and endothelial cells. It plays a role in angiogenesis, wound healing, cellular migration, and signal transduction.

Description: The UCHT2 monoclonal antibody specifically reacts with human CD5, a 67 kda type 1 transmembrane glycoprotein. CD5 is expressed on mature T cells, a subset of B cells, and peripheral blood dendritic cells. B cells that are CD5+ produce mostly IgM polyreactive antibodies. Its ligand is CD72, which is involved in T, B cell proliferation and interaction. The UCT2 antibody also recognizes non-human primate CD5.

Description: The BNI3 monoclonal antibody specifically reacts with human CD152, the Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4). CTLA-4 is expressed on activated CD28+ T cells, and binds the B7 family members B7-1 (CD80) and B7-2 (CD86). The structure of CTLA-4 is similar to the structure of CD28, but the two molecules seem to have opposite roles on the T lymphocytes. CTLA-4 inhibits the progression of T cell activation, while CD28 stimulates it. This result explains the stimulating role that the immobilization of BNI3 plays on the T lymphocytes proliferation induced by CD28.

Description: The GL-1 monoclonal antibody reacts specifically with the mouse B7-2 (also known as CD86), a costimulatory molecule expressed by B and T lymphocytes, macrophages (thioglycollate-induced from peritoneum), astrocytes and dendritic cells. The memory CD4+ T lymphocytes express CD86 (as mRNA and protein). CD86, and the B7-1 (CD 80) molecule, are ligands for CD152 and CD28, and influence the costimulatory interactions between lymphocytes B and T. B7-2 is also involved in the mouse natural killer cell-mediated cytotoxicity. The GL-1 antibody blocks the mixed lymphocyte reaction (MLR) and inhibits the T-cells stimulation by antigen-presenting cells. Mixtures of anti-B7-1 antibody and GL-1 were reported to inhibit the interaction between CD125 and its ligand with the in vivo priming of cytotoxic T lymphocytes.

Description: The HIB19 monoclonal antibody reacts with a human 95 kDa transmembrane glycoprotein known as CD19, which is expressed by B lymphocytes during all the developmental stages, except for the terminally differentiated plasma cells. CD19 is also expressed on follicular dendritic cells, and seems to ensure the regulation of B lymphocytes proliferation. CD19, CD21, CD81, MHC class II, and Leu13 can bind together and form a complex which associates with the B cell receptor (BCR) on the surface of B lymphocytes and facilitates the signal transduction.
