Notes
Block: In a functional ELISA which immobilized recombinant Human PD1/Fc Chimera (Catalog# 10377-H03H) at 1 μg/mL(100 µL/well) in the plate, the Human PD1 Monoclonal Antibody can block the binding of 1 μg/mL of biotinylated recombinant Human PD-L1 (Catalog# 10084-H02H-B) to human PD1, the EC50 is 0.5-1 μg/mL.
Neutralization: The neutralization activity of PD1 Neutralizing Antibody is Measured by its ability to neutralize PD1_PD-L1 pathway mediated inhibition of IFN-gamma secretion in the CD4+ T cells.
Please Note: Optimal concentrations/dilutions should be determined by the end user.

Effect of Human PD1 HN94 antibody on IFN-gamma production in the Mixed Lymphocyte Reaction (MLR). Purified CD4+ T cells were cultured with allogeneic dendritic cells, as prepared by culturing monocytes in GM-CSF and IL-4 medium for six days, in the medium containing serial concentrations of human PD1-HN94-IgG4 (Catalog# 10377-HN94). Five days later, the IFN-gamma production in the medium was evaluated (A), and the cell proliferation was measured by WST-8.assay (B).
Effect of Human PD1 HN94 antibody on IL-2 production in the Mixed Lymphocyte Reaction (MLR). Purified CD4+ T cells were cultured with allogeneic dendritic cells, as prepared by culturing monocytes in GM-CSF and IL-4 medium for six days, in the medium containing serial concentrations of human PD1-HN94-IgG4 (Catalog# 10377-HN94). Five days later, the IL-2 production in the medium was evaluated.
Safety information

PD-1 背景信息

Programmed cell death 1, also known as PDCD1, is a type I transmembrane glycoprotein, and is an immunoreceptor belonging to the CD28/CTLA-4 family negatively regulates antigen receptor signaling by recruiting protein tyrosine phosphatase, SHP-2 upon interacting with either of two ligands, PD-L1 or PD-L2. PD1 inhibits the T-cell proliferation and production of related cytokines including IL-1, IL-4, IL-1 and IFN-γ by suppressing the activation and transduction of PI3K/AKT pathway. In addition, coligation of PD1 inhibits BCR-mediating signal by dephosphorylating key signal transducer. PD1 has been suggested to be involved in lymphocyte clonal selection and peripheral tolerance, and thus contributes to the prevention of autoimmune diseases. Furthermore, PD1 is shown to be a regulator of virus-specific CD8+ T cell survival in HIV infection. As a cell surface molecule, PDCD1 regulates the adaptive immune response. Engagement of PD-1 by its ligands PD-L1 or PD-L2 transduces a signal that inhibits T-cell proliferation, cytokine production, and cytolytic function.
