IL15RA, also known as Interleukin 15 Receptor Alpha, is a high-affinity receptor for interleukin-15. IL15RA plays a role as a heterotrimer with the IL-2 receptor beta and gamma subunits to commence signal transduction. IL15/IL15R alpha complexes can transmit reverse signaling which promotes cellular adhesion, tyrosine phosphorylation of intracellular proteins, as well as cytokine secretion by the IL‑15/IL15R alpha expressing cells.
IL15RA produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain (31-205 a.a.) and fused to a 242 a.a. hIgG-His Tag at C-terminus containing a total of 417 amino acids and having a molecular mass of 45.6kDa.
IL15RA shows multiple bands between 57-70kDa on SDS-PAGE, reducing conditions and purified by proprietary chromatographic techniques.
IL15RA protein solution (0.5mg/ml) contains Phosphate buffered saline (pH7.4) and 10% glycerol.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 90.0% as determined by SDS-PAGE.
Determined by its ability to inhibit proliferation using CTLL2 mouse cytotoxic T cells. The ED50 for this effect is < 2 ng/ml with Human IL-15.
