General Notes
Mouse anti Sheep CD25, clone 9.14 recognizes the ovine homologue of human CD25, also known as interleukin-2 receptor alpha chain (IL-2Ra), a single pass type I membrane protein expressed by activated ovine T-cells.Ovine Interleukin-2 is a cytokine involved in the proliferation, growth and differentiation of T-cells, B-cells and NK cells and its receptor is composed of 3 subunits, an a chain (CD25), a ß chain (CD122) and a ? chain (CD132). A non-covalent association of the a and ß subunits is required to form the high affinity receptor for IL-2.Mouse anti sheep CD25, clone 9.14 immunoprecipitates a band of ~47 kDa under reducing conditions, as expected for the mature protein due to high glycosylation, consistent with the observed molecular weight of IL-2Ra in other species including humans (Verhagen et. al.1993).Antibodies to CD4, FoxP3 and CD25 may be used elucidate properties of T regulatory cells (T-regs), a unique subset of T helper cells that function in the control of effector cells vital in preventing autoimmunity (Rocchi et. al. 2011).Mouse anti sheep CD25, clone 9.14 is one of a wide range of monoclonal antibodies available from Bio-Rad for ovine research and provides an important tool for the identification of ovine CD25.
