CD25 Monoclonal Antibody (9.14), Invitrogen™

Description

• Mouse anti sheep CD25, clone 9.14 recognizes the ovine homologue of human CD25, also known as interleukin-2 receptor alpha chain (IL-2Rα), a single pass type I membrane protein expressed by activated ovine T-cells
• 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.
