Overview
IL2RA (Interleukin 2 receptor, alpha), also called IL2R, IL2R, Alpha Chain or CD25, is a protein that in humans is encoded by the IL2RA gene. The IL2RA gene is mapped on 10p15.1. IL2RA is composed of strand-swapped sushi-like domains, unlike the classical cytokine receptor fold. As a result of this domain swap, IL2RA uses a composite surface to dock into a groove on IL2 that also serves as a binding site for antagonist drugs. 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. Infection by the protozoan Trypanosoma cruzi causes Chagas disease, characterized by a reduction in the amount of IL2RA expressed on the surface of immune cells. This leads to chronic immune suppression, becoming increasingly severe over the course of many years and ultimately resulting in death if left untreated.
This anti-IL-2 receptor alpha antibody is supplied as Antigen affinity purified (Rabbit, Polyclonal (rabbit origin), Rabbit IgG, Unconjugated) and is designed to support common target-detection workflows after the on-page specifications.
Key elements and design rationale
- Target: IL-2 receptor alpha
- Format: Antigen affinity purified
- Localization: Cell surface, Cytoplasmic
- Species reactivity: Mouse, Rat
- Applications (listed): WB, IHC-P, FACS
- Conjugate: Unconjugated
- Clone and antibody class: Polyclonal (rabbit origin), Rabbit IgG
Because antibody performance can depend on epitope context, sample preparation, and biological state, interpret signals using appropriate controls and orthogonal evidence when possible.
Biological background
IL-2 receptor alpha is referenced in public gene/protein resources (e.g., UniProt and NCBI Gene), which provide curated names/synonyms, protein features, and pathway context. When designing assays, consider potential isoforms, post-translational modifications, and cell-type specific expression that may influence observed signal.
Research relevance and current trends
- Profiling IL-2 receptor alpha expression across model systems, perturbations, and time points to support mechanistic hypotheses.
- Combining antibody-based detection with multi-omics or imaging readouts to link IL-2 receptor alpha signal with phenotype.
- Using well-matched controls (isotype controls, genetic perturbations, or independent reagents) to strengthen interpretation of target-associated signal.
Common research applications
- WB
- IHC-P
- FACS
Use the listed applications as a starting point and tailor experimental design to your sample type and readout requirements.
Notes for experimental interpretation
- Specificity considerations: closely related family members, isoforms, or PTMs can affect apparent specificity; confirm with independent approaches when critical.
- Controls: include negative controls and, when feasible, genetic or pharmacologic perturbations to support target attribution in your system.
- Species and sample context: differences in sequence, expression, fixation, or extraction conditions can change signal behavior across models.
Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
