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 MR1 monoclonal antibody specifically reacts with mouse CD154, a 39kDA transmembrane glycoprotein also known as CD40 ligand and gp39. CD154 is expressed on activated T cells and plays a role in B-T cell costimulation. The interaction of CD154 with CD40 induces B cell cycle entry and the signaling for T-dependent B cell activation. By interfering with this interaction, the MR1 antibody is reported to inhibit T and B lymphocyte activation.

Description: The PK136 monoclonal antibody is specific for the MouseNK1.1, a receptor from the killer cell lectin-like receptor (KLR) family. Nk1.1 is an antigen encoded by the Klrb1c/NKR-P1C gene expressed by the natural killer cells of some selected strains of mice (C57BL, FVB/N, NZB) and encoded by the Klrb1b/NKR-P1B gene expressed on Swiss NIH and SJL mice. Pk136 binds to an epitoPEcommon to NKR-P1B and NKR-P1C.The Klrb1 is a family of tyPEII transmembrane C-tyPElectin receptors. Klrb1c activates the NK-cell cytotoxicity, while Klrb1b inhibits it. PK136 is useful in defining the NK cells and the rare population of NK-T lymphocytes and specific cultured monocytes.

Description: The MF23 monoclonal antibody specifically reacts with the mouse 50-55 kDa Foxp3 protein (JM2, IPEX), a member of the forkhead family of transcription factors. Foxp3 is expressed by the Treg lymphocytes, whose development and function are influenced by the forkhead protein. Ectopic expression of Foxp3 in T lymphocytes inhibits their activity and cytokine expression. Mutations of Foxp3 result in the “scurfy” mice phenotype. It is reported that the MF23 antibody recognizes an epitope between 1-87 amino acids in the N-terminal domain of mouse Foxp3.

Description: The 1316H monoclonal antibody binds to mouse IL-13. IL-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells, and also by mast cells and NK cells. Targeted deletion of IL-13 in mice resulted in impaired Th2 cell development and indicated an important role for IL-13 in the expulsion of gastrointestinal parasites. IL-13 exerts anti-inflammatory effects on monocytes and macrophages and it inhibits the expression of inflammatory cytokines such as IL-1β, TNF-α, IL-6 and IL-8. IL-13 has also been shown to enhance B cell proliferation and to induce isotype switching, resulting in increased production of IgE. Blocking of IL-13 activity inhibits the pathophysiology of asthma. The 1316H antibody is reported to be a neutralizing antibody.

Description: The MIH4 monoclonal antibody specifically reacts with human Programmed death-1 (PD-1 or CD279), a 50-55 kDA glycoprotein. It is expressed on mainly on activated B, T, and myeloid cells. Within the cytoplasmic region, PD-1 contains an Immunoreceptor tyrosine-based inhibitory motif (ITIM) and seems to regulate peripheral tolerance. The lack or mutation of CD279 is linked to autoimmune disorders.

Description: The RB6-8C5 monoclonal antibody reacts with the mouse Ly-6G (also known as Gr-1). The Ly-6G protein is a myeloid differentiation antigen of 21-25 kDa, expressed in a regulated manner by the myeloid lineage in the bone marrow, where the level of antigen expression is correlated with the granulocyte maturation and differentiation. In the bone marrow, the antigen is not expressed by the erythroid cells. From the peripheric cells, RB6-8C5 binds with monocytes, neutrophils and eosinophils.As a marker for the mouse monocytes, macrophages and granulocytes, the RB6-8C5 antibody is usually combined with M1/70, a macrophage labeling antibody (Anti-CD11b), for phenotypic analysis.

Description: The CD28.2 monoclonal antibody specifically binds with the human 44 kDa homodimeric trans-membrane glycoprotein CD28, expressed on the surface of most mature T lymphocytes, plasma cells, and thymocytes. CD28 is a ligand for B7-1 (CD80) and B7-2 (CD86), a co-stimulator of T lymphocytes, and enhances the interaction between T and B lymphocytes. It has been reported that the T lymphocytes stimulation to produce IL-2 depends on the monoclonal antibody involved, which suggests that the CD28 molecule presents some subregions with distinct functions. The CD28.2 antibody induces Ca2+ influx in Jurkat T lymphocytes. Other studies have shown that CD28 is involved in the signal transduction.

Description: The HP-3G10 monoclonal antibody specifically binds to an 80 kDa homodimer type II membrane glycoprotein from the C-type lectin superfamily, known as the human CD161 or NKR-P1A. CD161 is expressed on most natural killer cells, subsets of CD4+ and CD8+ T lymphocytes, γδ TCR T lymphocytes, a subset of CD3+ thymocytes, and especially on CD45RO+ T lymphocytes. Reports indicate that it may serve as a specific receptor for some natural killer cell targets and a possible stimulatory role.

Description: The 104 monoclonal antibody specifically reacts with the mouse CD45 molecule, the Leukocyte Common Antigen (LCA) which occurs in the alloantigen CD45.2-expressing mouse strains (C57BL/6, CBA, 129, A, AKR, C58, DBA/1, DBA/2, BALB/c, and C3H/He). The 104 monoclonal antibody does not react with the leukocytes of the CD45.1-expressing mouse strains (DA, SJL/J, RIII, and STS/A). 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. The 104 antibody inhibits some of the B lymphocytes responses, reduces the serum IgG levels, and influences the autoimmune renal pathology.

Description: The HI130 monoclonal antibody specifically reacts with the 180 kDa, 190 kDa, 205 kDa, and 220 kDa isoforms of the human leukocyte common antigen (LCA) CD45. It is expressed on lymphocytes, granulocytes, monocytes, thymocytes, and eosinophils, but not on mature erythrocytes, platelets, mature erythroid cells of bone marrow, and non-hematopoietic tissues. CD45 is essential for T cell activation and the tyrosine phosphatase activity of its intracellular region is integral for signal transduction.
