| Catalog Code: | NB100-63632 |
| Product Name: | CD25 Antibody |
| Product Description: | Mouse Monoclonal anti-CD25 (NDS 61), conjugated to FITC |
| Clone: | NDS 61 |
| Clonality: | Monoclonal |
| ListPrice: | 295 |
| Concentration: | 0.1 mg/ml |
| Immunogen: | Rat IL-2 receptor |
| Specificity: | NB100-63632 recognises the rat CD25 cell surface antigen, a 55kD molecule that is the low affinity alpha chain of the IL-2 receptor. NB100-63632 recognises a different epitope on CD25 to the OX39 clone. Clone NDS 61 is reported to block IL-2 induced cell proliferation (2). |
| Cross Reactivity: | Rat. Not yet tested in other species. |
| Packaging: | 0.1 mg Mouse ascites. |
| Uses: | This antibody is useful for flow cytometry / FACS analysis |
| Background: | The IL2 receptor (IL2R) exists in three alternative forms made up from the individual components of CD25, CD122, and CD132. CD25 represents the low affinity alpha chain of the IL2R, a type I transmembrane glycoprotein containing two CCP domains. It is rich in O linked carbohydrates and has a short cytoplasmic tail. CD25 is expressed on activated T cells, B cells, NK cells and monocytes of all mouse strains tested. It is transiently expressed at a low level during B cell development in bone marrow on the CD45R/B220 low TdT- sIg- pre-B II and CD45R/B220low TdT- sIgM+sIgD- immature B cells, but not on the CD45R/B220 low TdT+ sIg- pro-B/pre B I stage nor on CD45R/B220high TdT- sIgM+sIgD+ mature B cells. CD25 is expressed at a higher level during very early T cell development in fetal and adult thymus. |
