Description: The J43.1 monoclonal antibody specifically reacts with mouse CD279, also known as PD-1 (programmed death-1), a 50-55 kDa glycoprotein of the Ig superfamily. The PD-1 ligands, PD-L1 (B7-H1) and PD-L2 (B7-H2) are members of the B7 family. Pd-1 contains an Immunoreceptor Tyrosine-based Inhibitory Motif (ITIM) and influences the peripheral tolerances and autoimmune diseases in mice. PD-1 is transiently expressed on CD4/CD8 thymocytes, it is upregulated in apoptotic cells, and it is expressed by activated myeloid and T and B cells. The binding of PD-1 to its ligands is blocked by the J43 antibody, which also enhances contact hypersensitivity and exacerbates acute Graft-versus-host disease, Experimental autoimmune encephalomyelitis and NOD diabetes. PD-1 seems to downregulate the immune response, as the development of splenomegaly and breakdown of peripheral tolerance in PD-1 deficient mice suggests.

Description: The 3D12 monoclonal antibody specifically reacts with human CD197 (CCR7 or EBI-1), a seven-transmembrane G-protein-coupled. It is the receptor for the secondary lymphoid-tissue chemokine (SLC or 6CKine), CCL19, and CCL21. CD197 is expressed on subsets of B and T cells, and mature dendritic cells. The monoclonal 3D12 antibody recognizes the N-terminus of the receptor.
We recommend that this antibody be incubated for at least 45 minutes at 4°C for optimal staining.

Description: The 4S.B3 is a neutralizing antibody that binds with the human Interferon-gamma (IFN-γ) protein, a 15 -17 kDa cytokine with significant antibacterial, antiviral, and antitumoral properties. When secreted by natural killer cells and by natural killer T lymphocytes, it regulates the immune response and supports adaptive immunity when produced by Th1 or CD8+ T lymphocytes. IFN-γ plays an important role in the activation, the growth, and the differentiation of the macrophages, B and T lymphocytes, and natural killer cells. It interacts synergically with other cytokines, such as TNF-α, to inhibit proliferation of normal and transformed cells. IFN- γ is the primary cytokine that defines Th-1 cells. The biological activity of IFN-γ is not affected by glycosylation.

Description: The 4S.B3 monoclonal antibody specifically reacts with human interferon gamma, a multifunctional cytokine that is produced mainly by activated T and NK cells. Interferon gamma has anti-viral and anti-parasitic properties and plays an important role in the activation, growth, and differentiation of macrophages, B and T lymphocytes, and natural killer cells. It interacts synergically with other cytokines, such as TNF-α, to inhibit proliferation of normal and transformed cells. The 4S.B3 antibody neutralizes IFN-γ.

Description: The MP4-25D2 monoclonal antibody specifically reacts with human Interleukin-4 (IL-4), expressed by the activated T cells and mast cells. IL-4 is species-specific and stimulates the proliferation and differentiation of B lymphocytes. It upregulates the expression of IgE receptors and class II MHC antigen. The MP4-25D2 is a neutralizing antibody and is reported to be cross-reactive with rhesus monkeys.

Supplier: BIOGEMS INTERNATIONAL INC.

Description: The R4-6A2 monoclonal antibody specifically reacts with mouse interferon gamma (IFN-g), an acid-labile interferon produced by CD4 and CD8 T lymphocytes as well as activated NK cells. IFN gamma receptors are present in most immune cells, which respond to its signaling by increasing the surface expression of class I MHC proteins. This promotes the presentation of antigen to T-helper (CD4+) cells. Additionally, it stimulates a number of lymphoid cell functions, including the anti-microbial and anti-tumor responses of macrophages, NK cells, and neutrophils.
