CD25 antibodies, mouse

CD25 antibodies, mouse

Clone: REA568 | Dilution: 1:10
Clone REA568 recognizes the mouse CD25 antigen, the α chain of the IL-2 receptor (IL-2R). IL-2Rα associates with the β chain (CD122) and the γ chain (CD132) to form the functional IL-2R complex. IL-2Rα is expressed on CD4
regulatory T cells, activated T and B cells, and to a lesser extent on activated dendritic cells. It is also transiently expressed during T and B cell development. Binding of the CD25 antibody does not impede the binding of IL-2 to its receptor. In combination with CD4, CD25 antibody can be used to identify regulatory T cells (Tregs).
Additional information: Clone REA568 displays negligible binding to Fc receptors.

Alternative names
