Anti Mouse CD25 mAb, Carrier-free (BSA/Glycerol-free)

mCD25

The antibody reacts with mouse CD25, the 55 kDa interleukin-2 receptor alpha chain (IL-2R alpha). CD25 is expressed by early progenitors of the T and B lineage as well as by activated mature T and B lymphocytes. By itself, CD25 binds IL-2 only with low affinity. However, CD25 associates with CD122 (IL-2 receptor beta chain) and CD132 (common gamma chain) to form the high affinity IL-2 receptor. Binding of IL-2 to both the high and low affinity classes of IL-2 receptor is inhibited by the PC61.5 antibody. CD25 plays a role in lymphocyte differentiation and activation/proliferation.We constantly strive to ensure we provide our customers with the best antibodies. As a result of this work we offer this antibody in purified format. We are in the process of updating our datasheets.

Il2ra, Mus musculus (Mouse)

IL-2 receptor alpha (IL-2 R alpha ), also known as CD25, is a 55 kDa type I membrane glycoprotein that belongs to the family of cytokine receptors that utilize the common gamma chain subunit ( gamma c). IL-2 R alpha is primarily expressed on activated T cells and on regulatory T cells (Treg). The mouse IL-2 R alpha cDNA encodes a 268 amino acid (aa) precursor that includes a 21 aa signal peptide, a 215 aa extracellular domain (ECD) with two Sushi domains, a 21 aa transmembrane segment, and an 11 aa cytoplasmic domain. Within the ECD, mouse IL-2 R alpha shares 81% and 58% aa sequence identity with rat and human IL-2 R alpha, respectively. It shares approximately 15% aa sequence identity with IL-4, -7, -9, -15, and -21 receptor subunits that also complex with gamma c. IL-2 R beta (CD122) and gamma c (IL-2 R gamma /CD132) dimerize to form a constitutively expressed intermediate affinity IL-2 receptor. By itself, IL-2 R alpha binds IL-2 with low affinity. It associates with IL-2 R beta and gamma c to generate a ternary high affinity IL-2 receptor complex. A soluble form of IL-2 R alpha can be generated by proteolytic cleavage of the cell surface receptor, rendering the T cell unresponsive to IL-2. Increased serum levels of soluble IL-2 R alpha are found in some cancers and immune disorders. IL-2 R alpha is required for activation induced cell death (AICD) of naive T cells, a mechanism responsible for deleting autoreactive T cell clones. IL-2 R alpha is also required for the development of CD4+CD25+ Treg which suppress autoreactive CD4+ T cells, thereby contributing to peripheral T cell homeostasis.
