Description

Description: This P4A10 monoclonal antibody reacts with canine CD25, the 55-kDa interleukin-2 receptor alpha (IL-2R\alpha) chain. As in humans and mice, CD25 in dogs is expressed by early T and B lineage progenitors as well as by activated mature T and B lymphocytes. CD25 associates with the IL-2R beta (CD122) and gamma (CD132) chains to form the high-affinity IL-2 receptor. On its own, CD25 binds IL-2 with low affinity. Along with CD4 and Foxp3, CD25 is a major marker used to define regulatory T cells. The P4A10 antibody has been reported to recognize the same epitope as the anti-human CD25 monoclonal antibody ACT-1, but with greater affinity. Applications Reported: This P4A10 antibody has been reported for use in flow cytometric analysis. Applications Tested: This P4A10 antibody has been pre-titrated and tested by flow cytometry on normal canine peripheral blood cells. This can be used at 5 μL (0.125 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: 488 nm; Emission: 520 nm; Laser: Blue 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 μgcerative 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.
