| Product Name: | CD25 Antibody |
| Product Description: | Mouse Monoclonal anti-CD25 (MEM-181), conjugated to APC |
| Clone: | MEM-181 |
| Clonality: | Monoclonal |
| ListPrice: | 340 |
| Gene ID: | 10p15-p14 |
| Reference Sequence: | 10p15-p14 |
| Immunogen: | PHA-activated peripheral blood leucocytes |
| Specificity: | The antibody MEM-181 reacts with CD25 (Interleukin-2 receptor a chain), a 55 kDa type I transmembrane glycoprotein expressed on activated B and T lymphocytes, activated monocytes/macrophages and on CD4+ T lymphocytes (T regulatory cells); it is lost on resting B and T lymphocytes. HLDA VI; WS Code NL N-L024 |
| Cross Reactivity: | Human. Not tested in other species. |
| Packaging: | 100 tests Mouse ascites. |
| Uses: | The reagent is designed for Flow Cytometry analysis of human blood cells using 20 mlreagent / 100 ml of whole blood or 10^6 cells in a suspension.The content of a vial (2 ml) is sufficient for 100 tests. |
| Background: | CD25 (IL2Ralpha, Tac) is a ligand-binding alpha subunit of interleukin 2 receptor (IL2R). Together with beta and gamma subunit CD25 constitues the high affinity IL2R, whereas CD25 alone serves as the low affinity IL2R. CD25 expression rapidly increases upon T cell activation. The 55 kDa CD25 molecule is enzymatically cleaved and shed from the cell surface as a soluble 45 kDa s-Tac, whose concentration in serum can be used as a marker of T cell activation. Expression of CD25 indicates the neoplastic phenotype of mast cells. Humanized anti CD25 antibodies represent a useful tool to reduce the incidence of allograft rejection as well as the severity of graft versus host reaction, and radioimmunoconjugates of anti-CD25 antibodies can be used against CD25 expressing lymphomas. |
| Storage: | Store in the dark at 2-8C. Do not freeze. Avoid prolonged exposure to light. Do not use after expiration date stamped on vial label. Short-term exposure to room temperature should not affect the quality of the reagent. However, if reagent is stored under |
