Activity Data
(IL2RA (Interleukin-2 receptor alpha chain ), also known as Tac antigen and as CD25, was initially identified as a 55kDa membrane glycoprotein which is capable of binding IL 2. Besides, mouse IL2 shares 75.1% AA sequence identity with rat IL2, suggesting the exist of cross-species activity. Thus we have conducted a binding ELISA assay to detect the interaction of recombinant rat IL2RA with recombinant mouse IL2. Briefly, IL2RA were diluted serially in PBS, with 0.01%BSA (pH 7.4). Duplicate samples of 100uL were then transferred to IL2-coated microtiter wells and incubated for 2h at 37 degree C. Wells were washed with PBST and incubated for 1h with anti-IL2RA pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody, wells were aspirated and washed 3 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37 degree C. Finally, add 50uL stop solution to the wells and read at 450nm immediately. The binding activity of IL2RA with IL2 was shown in Figure 1 and this effect was in a dose dependent manner.)

Product Notes
The IL2Ra il2ra (Catalog #AAA2097348) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The Active Interleukin 2 Receptor Alpha (IL2Ra) reacts with Mouse and may cross-react with other species as described in the data sheet. AAA Biotech's Interleukin 2 Receptor Alpha (IL2Ra) can be used in a range of immunoassay formats including, but not limited to, Cell culture, Activity Assays. Researchers should empirically determine the suitability of the IL2Ra il2ra for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Interleukin 2 Receptor Alpha (IL2Ra), Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
