Species Reactivity
Human
Specificity
Detects human CD25/IL-2 R alpha in ELISAs and Western blots. In Western blots, detects recombinant rat CD25/IL-2 R alpha but no cross-reactivity with recombinant mouse CD25/IL-2 R alpha. In sandwich immunoassays, this antibody does not cross-react or interfere with recombinant human (rh) IL-1 RI, rhIL-1 RII, rhIL-2 R beta, rhIL-3 R alpha, rhIL-4 R, rhIL-5 R alpha, rhIL-5 R beta, rhIL-6 R, or rhgp130.

Data Examples
Western Blot | Detection of Recombinant Human and Rat CD25/IL-2 R alpha by Western Blot. Western blot shows 25 ng of Recombinant Human CD25/IL-2 R alpha (Catalog # ), Recombinant Mouse CD25/IL-2 R alpha (Catalog # ) and Recombinant Rat CD25/IL-2 R alpha Fc Chimera (Catalog # ). PVDF Membrane was probed with 1 µg/mL of Mouse Anti-Human CD25/IL-2 R alpha Monoclonal Antibody (Catalog # MAB623) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # ). Specific bands were detected for CD25/IL-2 R alpha at approximately 30-250 kDa (as indicated). This experiment was conducted under non-reducing conditions and using . |
Immunocytochemistry | CD25/IL‑2 R alpha in Human PBMCs. CD25/IL‑2 R alpha was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) stimulated with PHA using Mouse Anti-Human CD25/IL‑2 R alpha Monoclonal Antibody (Catalog # MAB623) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (yellow; Catalog # ) and counterstained with DAPI (blue). Upper panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents. View our protocol for . |
Immunohistochemistry | CD25/IL‑2 R alpha in Human Lymph Node. CD25/IL‑2 R alpha was detected in immersion fixed frozen sections of human lymph node using 15 µg/mL Mouse Anti-Human CD25/IL‑2 R alpha Monoclonal Antibody (Catalog # MAB623) overnight at 4 °C. Tissue was stained (red) and counterstained with hematoxylin (blue). View our protocol for . |

Background: CD25/IL-2 R alpha
IL-2 R alpha is a type I transmembrane protein that associates with IL-2 R beta and the common gamma chain to form a high affinity heterotrimeric receptor complex for IL-2. A soluble form of IL-2 R alpha has been detected in serum.
