Attributs du produit: The 7D4 antibody reacts with CD25, the low affinity IL-2 Receptor (IL-2Rα, p55) expressed on activated T and B lymphocytes from all mouse strains tested. IL-2Rα by itself is not a signaling receptor. However, it can combine with IL-2 Receptor β (CD122) and γ (CD132) chains to form high-affinity, signaling receptor complexes for IL-2. Resting T and B lymphocytes and resting and activated NK cells do not express IL-2Rα. CD25 is transiently expressed at a low level during normal B-cell development in the bone marrow on the CD45R/B220low TdT- sIg- Pre-B/Pre-B-II and CD45R/B220low TdT- sIgM+ sIgD- immature B stages, but not on the CD45R/B220low TdT+ sIg- Pro-B/Pre-B-I stage nor on CD45R/B220high TdTsIgM+ sIgD+ mature B cells. It is expressed at a higher level during a very early stage of T-cell development in fetal and adult thymus. Peripheral CD25+ CD4+ T lymphocytes called regulatory T (Treg) cells are involved in the maintenance of self-tolerance. It has also been reported that dendritic cells express CD25, recognized by mAb 7D4 (Cat. no. 553068). The 3C7 antibody recognizes an epitope of CD25 which is distinct from those recognized by mAbs 7D4 and PC61 (Cat. no. 553866), and it blocks binding of IL-2 to CD25. This antibody is routinely tested by flow cytometric analysis. Other applications were tested during antibody development only or reported in the literature. Two-color analysis of the expression of CD25 in bone marrow. BALB/c bone marrow leukocytes were simultaneously stained with biotin-conjugated 7D4 (right panel) and FITC-conjugated RA3-6B2 (anti-mouse CD45R/B220, Cat. No. 553087/553088, both panels) monoclonal antibodies, followed by Streptavidin-PE (Cat. No. 554061, both panels). Flow cytometry was performed on a BD FACScan™
