Mouse monoclonal antibody raised against native IL2RA.
Native purified IL2RA from PHA-activated peripheral blood leucocytes.
Theoretical MW (kDa):
This antibody reacts with CD25 (Interleukin-2 receptor alpha 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.
The optimal working dilution should be determined by the end user.
In PBS, pH 7.4 (0.09% sodium azide)
Store at 4°C. Do not freeze. Aliquot to avoid repeated freezing and thawing.
This product contains sodium azide: a POISONOUS AND HAZARDOUS SUBSTANCE which should be handled by trained staff only.
Surface staining of human PBMC with IL2RA monoclonal antibody, clone MEM - 181 (Cat # MAB0882) FITC. The mononuclear cells were isolated from human peripheral blood, devided in aliquots for duplicate analysis and stimulated with PHA for 2 days. Panel A, C - Staining with the IL2RA monoclonal antibody, clone MEM - 181 (Cat # MAB0882). Panel B, D - staining with the standard anti - IL2RA monoclonal antibody.
The interleukin 2 (IL2) receptor alpha (IL2RA) and beta (IL2RB) chains, together with the common gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric alpha chains (IL2RA) result in low-affinity receptor, while homodimeric beta (IL2RB) chains produce a medium-affinity receptor. Normally an integral-membrane protein, soluble IL2RA has been isolated and determined to result from extracellular proteolyisis. Alternately-spliced IL2RA mRNAs have been isolated, but the significance of each is presently unknown. [provided by RefSeq
