CD25 Antibody IL2RA/2393 Detects IL2RA in Ramos, HeLa and Jurkat Cells WB. Western blot analysis of human Ramos B lymphocyte, HeLa cervical cancer, and Jurkat T lymphocyte cell lysates using CD25 Antibody clone IL2RA/2393 detects a strong, discrete band at approximately 36 kDa in all three samples, with minimal additional background. CD25 is a glycosylated cell-surface protein whose electrophoretic migration can vary with glycosylation state. The consistent band across three distinct human cell lines demonstrates detection of IL2RA by this IL2RA Monoclonal Antibody under Western blot conditions.
SDS-PAGE analysis of purified, BSA-free CD25 antibody (clone IL2RA/2393) as confirmation of integrity and purity.
Analysis of HuProt(TM) microarray containing more than 19,000 full-length human proteins using CD25 antibody (clone IL2RA/2393). These results demonstrate the foremost specificity of the IL2RA/2393 mAb. Z- and S- score: The Z-score represents the strength of a signal that an antibody (in combination with a fluorescently-tagged anti-IgG secondary Ab) produces when binding to a particular protein on the HuProt(TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If the targets on the HuProt(TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-scores. The S-score therefore represents the relative target specificity of an Ab to its intended target.

Description

CD25 Antibody IL2RA/2393 recognizes CD25, the alpha subunit of the interleukin 2 receptor encoded by the IL2RA gene. CD25 is a type I transmembrane glycoprotein expressed prominently by activated T and B lymphocytes and by regulatory T cells. As part of the IL-2 receptor system, CD25 contributes to cellular responses to interleukin 2 and plays an important role in lymphocyte activation, proliferation, survival, and immune homeostasis.

CD25 functions independently as a low-affinity receptor for IL-2. Association with IL2RB (CD122) and the common gamma chain IL2RG (CD132) forms the high-affinity IL-2 receptor complex. Although CD25 itself does not provide the principal intracellular signaling activity of the receptor, its ability to capture IL-2 increases receptor affinity and facilitates signaling through pathways including JAK-STAT, PI3K-AKT, and MAPKs.

IL2RA expression is induced following activation of conventional lymphocytes and is characteristically high on regulatory T cells. IL-2 signaling through CD25-containing receptors is particularly important for regulatory T-cell development, maintenance, and suppressive activity. CD25 is therefore widely studied in immune activation and tolerance, inflammatory responses, and hematologic malignancies. Soluble CD25 can also be released from cells and has been investigated as a marker of immune-system activation.

Clone IL2RA/2393 is a mouse monoclonal antibody generated using stimulated human leukocytes as the immunogen. It recognizes epitope region B within the N-terminal portion of CD25 and can block IL-2 binding to CD25. The antibody has also been evaluated on a HuProt protein microarray containing more than 19,000 full-length human proteins to assess target specificity. As an IL2RA Monoclonal Antibody, clone IL2RA/2393 provides a defined reagent for investigating this important component of the IL-2 receptor system. NSJ Bioreagents supplies IL2RA/2393 for research use only.

A CD25 Antibody can be used to investigate IL2RA expression and molecular mechanisms connecting IL-2 receptor biology, lymphocyte activation, regulatory T-cell function, and immune regulation.
