ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Specificity

Clone 1K6 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects IL-2 receptor subunit alpha (CD25). It targets an epitope within 119 amino acids from the N-terminal region.

Immunogen

GST/His-tagged recombinant fragment corresponding to 119 amino acids from the N-terminal, extracellular domain of human IL-2 receptor subunit alpha (CD25).

Application

Anti-CD25 (IL2-RA), clone 1K6 ZooMAb, Cat. No. ZRB1412, is a recombinant Rabbit monoclonal antibody that targets CD25 (IL2-RA) and is tested for use in Flow Cytometry, Immunohistochemistry (Paraffin), and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected CD25 (IL2-RA) in human lymph node tissue lysate.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected CD25 (IL2-RA) in human tonsil tissue sections.

Flow Cytometry Analysis: 1μg from a representative lot detected CD25 (IL2-RA) in one million human peripheral blood mononuclear cells (PBMC).

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Target description

Interleukin-2 receptor subunit alpha (UniProt: P01589; also known as IL-2 receptor subunit alpha, IL-2-RA, IL-2R subunit alpha, IL2-RA, TAC antigen, p55, CD25) is encoded by the IL2RA gene (Gene ID: 3559) in human. IL-2-RA is a non-covalent dimer of an alpha (CD25), beta unit (CD122). IL-2-RA is involved in the regulation of immune tolerance and controls the activity of T cells. IL-2RA can exist in three different forms; a high affinity dimer, an intermediate affinity monomer of beta subunit, and a low affinity monomer of alpha subunit. The high and intermediate affinity forms can also associate with a gamma subunit (CD132). CD25 is rapidly up-regulated upon activation of T cells. Activated T cells, regulatory T cells (Tregs) and NK cells express high levels of CD25, and high affinity expression of IL-2-RA is largely limited to these cells. CD25 is a single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-21), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 22-240), a transmembrane domain (aa 241-250), and a short cytoplasmic tail (aa 260-272). It also contains two Sushi domains (aa 22-84 and 123-186). Mutations in IL2RA gene have been linked to insulin-dependent diabetes mellitus and immunodeficiency with lymphoproliferation that leads to recurrent viral, fungal, and bacterial infections. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
