Description: 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.

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.

Description: The AK-4 monoclonal antibody specifically reacts with human CD62P (P-Selectin), a 140 kDA type I transmembrane glycoprotein also known as platelet activation-dependent granule membrane protein (PADGEM). 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.

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 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 Sa2-8 monoclonal antibody specifically reacts with mouse CD14, a cell surface anchored glycoprotein that is primarily expressed on macrophages and is secreted in certain conditions. CD14 associates with LPS and LBP to form a receptor complex, which signals specifically in response to bacterial lipopolysaccharide (LPS) binding. The Sa2-8 antibody exhibits a weak antagonistic activate in relation to TNF alpha production and NF-kappa B activation.

Description: The 61D3 monoclonal antibody specifically reacts with CD14, a cell surface anchored glycoprotein that is primarily expressed on monocytes, inerfollicular macrophages, and a subset of dendritic cells. CD14 associates with MD-2 (LY-96) and TLR4 to form a receptor complex, which signals specifically in response to bacterial lipopolysaccharide (LPS) binding. The CD14/MD-2/TLR4 receptor complex signals via MyD88, TIRAP, and TRAF6, and ultimately activates NF-kappaB.

Description: The UC10-4F10-11 monoclonal antibody specifically reacts with the mouse Cytotoxic T-Lymphocyte Antigen-4 (CTLA-4), also known as CD152. It is a protein with a structure similar to CD28 regarding the genomic organization, amino acid sequence, and structure. CTLA-4 is expressed on activated T cells and CD25+/CD4+ Treg lymphocytes and binds the members of the B7 family, B7-1 (CD80) and B7-2 (CD86), with higher affinity than CD28. CD28 seems to provide opposing signal to T lymphocytes, while CD152 inhibits the T lymphocytes progression to an activated state and their proliferation, CD28 is a costimulator. The mouse UC10 -4F10-11 monoclonal antibody does not cross-react with the rat leukocytes.

Description: The 53-6.7 monoclonal antibody specifically reacts with Ly-2, the 38 kDa alpha chain, and with Lyt-2, the 34 kDa alpha’ chain, of the mouse CD8 antigen. The alpha’ chain is the truncated form of alpha chain, encoded by the same CD8a gene. In CD8a, the alpha and 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. Its function seems to be to attenuate the CD8-mediated signal for the stimulation of intrathymic T-cell maturation.The 53-6.7 antibody is useful for depleting CD8+ peripheral T lymphocytes. It cross reacts with the alpha- and alpha’-like polypeptides on some thymic and peripheral lymphocytes.

Description: The 3H5 monoclonal antibody reacts with mouse CD80, also known as B7-1, a 55 kDa type I transmembrane protein ligand for CD152 (CTLA-4) and for CD28, a co-stimulatory receptor for the T cell receptor (TCR). CD28 also binds a second B7 ligand known as CD86 (B7-2). Both CD80 and CD86 are expressed on activated B cells and antigen-presenting cells. These ligands trigger CD28 signaling in concert with TCR activation to drive T cell proliferation, induce high-level expression of IL-2, impart resistance to apoptosis, and enhance T cell cytotoxicity. The interaction / co-stimulatory signaling between the B7 ligands and CD28 or CTLA-4 provides crucial communication between T cells and B cells or APCs to coordinate the adaptive immune response.
The 3H5 antibody block the binding of CD80 to its ligands.

Description: The DTA-1 monoclonal antibody specifically reacts with MouseGlucocorticoid-Induced TNFR-related protein, also known as GITR and TNFRSF18, a 66-70 kDa homodimer glycoprotein, detected in the T cells treated with glucocorticoid dexamethasone. GITR is also expressed in naïve mice by CD25+/CD4+/CD8a- thymocytes and on CD25+/CD4+/CD45RB-low splenocytes. Low levels were detected in splenic CD25+/CD4+/CD45RB-low T cells, B cells, dendritic cells and macrophages. A GITR ligand was detected on dendritic cells, macrophages and B cells.The DTA-1 antibody stimulates GITR and abrogates suppression by T regulatory cells (Treg), without affecting their proliferation. DTA-1 administration or the removal of GITR-expressing cells led to organ specific autoimmune disease.

Description: The UT41 monoclonal antibody specifically reacts with mouse CD284, a 110kDA type I transmembrane signaling molecule known as the Toll-like Receptor 4 (TLR4). The complex of TLR-4, MD-2, and CD14 regulates the innate immune system recognition of bacterial lipopolysaccharides (LPS) and is expressed on the surface of thioglycollate-elicited macrophages. The UT41 antibody can bind to TLR4 with or without the formation of the TLR4/MD-2 complex.

Description: 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.
