IL2RA, commonly known as CD25, serves as the alpha subunit of the high-affinity interleukin-2 receptor and plays a pivotal role in immune regulation. This surface marker is essential for understanding T cell activation, regulatory T cell biology, and immune checkpoint mechanisms, making it a critical target for researchers investigating autoimmune disorders, transplant rejection, and cancer immunotherapy.
This recombinant monoclonal antibody against human IL2RA offers the consistency and reliability that demanding immunology research requires. Produced using recombinant technology with a defined sequence, this antibody eliminates the lot-to-lot variability that can compromise longitudinal studies and reproducibility. The 5F10 clone is expressed as a human IgG1 isotype and undergoes affinity chromatography purification, ensuring high purity for your downstream applications.
Functional validation demonstrates exceptional binding characteristics, with ELISA testing showing an EC50 in the low nanogram per milliliter range when binding to immobilized human IL2RA protein. This high-affinity interaction translates directly to reliable target detection in your experiments. For immunofluorescence applications, this antibody has been validated in both HeLa and HepG2 cell lines at dilutions of 1:30, with recommended working dilutions ranging from 1:20 to 1:200 depending on your specific experimental conditions. The clear membrane and cytoplasmic staining patterns observed in validation studies confirm specific target recognition.
Supplied in a glycerol-based PBS buffer optimized for long-term stability at -20°C or -80°C, this antibody is well-suited for researchers exploring IL-2 signaling pathways, regulatory T cell characterization, and immune response modulation. Whether you are investigating basic immune mechanisms or developing translational applications, this antibody provides the specificity and reproducibility your work demands.
