CD122 Rat anti-Mouse, APC, Clone: TM-Beta 1, BD, Rat Monoclonal Antibody, Each

Details

The TM- β 1 antibody reacts with the 90-100-kDa β chain shared by the IL-2 and IL-15 receptors (IL-2R β , CD122). In the periphery, CD122 is expressed on CD8 T lymphocytes, NK cells, NK-T cells, dendritic epidermal T cells, subsets of intraepithelial lymphocytes, and macrophages. Small subsets of fetal and adult thymocytes constitutively express CD122. CD122 cells in the bone marrow include committed NK-cell progenitors. IL-2R β expression is upregulated by IL-2. CD122 is a transmembrane glycoprotein of the hematopoietin receptor superfamily which can combine with CD132 ( γc) alone or CD132 plus CD25 (IL-2R α ) to form intermediate or high-affinity IL-2 receptor complexes, respectively. The β chain of these complexes, CD122, is involved in signal transduction and immunoregulation. The TM- β 1 antibody blocks high affinity binding of IL-2 or IL-15 to IL-2R β .
