Description: This CD25-4E3 monoclonal antibody reacts to human CD25, which is also known as the low-affinity interleukin (IL)-2 receptor alpha. CD25 is expressed on activated T cells (including a subset of regulatory T cells), B cells, and macrophages. This receptor subunit associates with CD122, the IL-2 receptor beta chain, and CD132, the common gamma chain, to form the high-affinity IL-2 receptor. IL-2 receptor signaling has been linked to cell proliferation and survival in lymphocytes. CD25 is a marker for Hodgkin's disease, and has been associated with such autoimmune diseases as Type I diabetes.
This monoclonal antibody is cross-reactive to rhesus monkey.
Applications Reported: This CD25-4E3 antibody has been reported for use in flow cytometric analysis.
Applications Tested: This CD25-4E3 antibody has been pre-titrated and tested by flow cytometric analysis of nrmal human peripheral blood cells. This can be used at 5 µL (0.06 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.
Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser.
Filtration: 0.2 µm post-manufacturing filtered.
CD25 (IL2 receptor alpha chain/IL2RA) is a cytokine that plays a role in the proliferation of T and B lymphocytes. The receptor of this cytokine (IL2RA) is a heterotrimeric protein complex with a gamma chain also shared by interleukin 4 (IL4) and interleukin 7 (IL7). IL2RA, IL2R beta chain (IL2RB), and the IL2R gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric IL2RA chains result in low-affinity receptor, while homodimeric IL2RB chains produce a medium-affinity receptor. The expression of IL2 in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene. IL2 is primarily produced by mature T cells. IL2 plays an important role as a growth factor, differentiation factor, and regulator of cell death. IL-2 stimulates the proliferation of B cells, augments natural killer cell activity, and inhibits granulocyte macrophage colony formation. The targeted disruption of a similar gene in mice leads to ulcerative colitis-like disease, which suggests a role in the immune response to antigenic stimuli. Mutations in this gene are associated with interleukin 2 receptor alpha deficiency.
