Reactivity Species
Host Species
Purified Recombinant Human IL-2 Rα (>98%)
This biotinylated antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.4 containing 50 µg of bovine serum albumin per µg of antibody with no calcium, magnesium, or preservatives present.
Storage and Handling
The lyophilized, biotinylated antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for up to twelve months from date of receipt. The reconstituted biotin conjugate can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted conjugate, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Applications and Recommended Usage?
Quality Tested by Leinco
Western Blotting: To detect Human IL-2 Rα this biotin conjugate can be used at a concentration of 0.1 - 0.2 µg/ml. This biotin conjugate should be used in conjunction with compatible second-step reagents such as PN:A106 and a chromogenic substrate such as PN:T343. The detection limit for Human IL-2 Rα is 5 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used. A suitable Western blotting control is PN:I-139.
ELISA Sandwich Assay: This antibody can be used as the detection antibody in a sandwich ELISA at a concentration of approximately 0.1-0.4 µg/ml when used in conjunction with PN:I-167 as the capture antibody at 2 - 8 µg/ml and an optimal second step reagent such as PN:A106 for the detection of Human IL-2 Rα.
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.


Goat Anti-Human Interleukin-2 Receptor Alpha (IL-2 Rα) recognizes Human IL-2 Rα. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.
IL-2 receptor alpha chain (IL-2Ralpha) is a component of high-affinity IL-2 receptors and thus is a key regulator of lymphocyte proliferation.1 IL-2R alpha expression occurs at specific stages of early T and B lymphocyte development and is induced upon activation of mature lymphocytes. IL-2R alpha is essential for regulation of both the size and content of the peripheral lymphoid compartment, probably by influencing the balance between clonal expansion and cell death following lymphocyte activation.2 IL-2Ralpha is also important in the formation of high-affinity binding sites, and the inducibility of the alpha gene contributes to the highly regulated and transient display of high-affinity IL-2R.3
