Low affinity alpha chain IL-2 receptor (IL-2R alpha), Mr 55 kDa
The IL-2 receptor (IL-2R) exists in three alternative forms made up from the individual components of CD25, CD122, and CD132. CD25 represents the low affinity alpha chain of the IL-2R, a type I transmembrane glycoprotein containing two CCP domains. It is rich in O-linked carbohydrates and has a short cytoplasmic tail.^2 CD25 is expressed on activated T cells, B cells, NK cells and monocytes of all mouse strains tested.^1, 3, 4 It is transiently expressed at a low level during B-cell development in bone marrow on the CD45R/B220^low TdT^- sIg^- pre-B II and CD45R/B220^low TdT^- sIgM^+sIgD^- immature B cells, but not on the CD45R/B220^low TdT^+ sIg^- pro-B/pre-B I stage nor on CD45R/B220^high TdT^- sIgM^+sIgD^+ mature B cells.^5, 6 CD25 is expressed at a higher level during very early T-cell development in fetal and adult thymus.^6, 7 The 7D4 monoclonal antibody reacts with an epitope between amino acids 125 and 212 that is distinct from that recognized by the monoclonal antibody 3C7 (Cat. No. 1600-XX). While the monoclonal antibody 7D4 does not block the binding of IL-2 to CD25, when used in combination with the monoclonal antobody 3C7 it results in higher levels of inhibition of IL-2-driven proliferation than either of these two monoclonal antibodies alone.^3, 8, 9
