background Interleukin 15 Receptor alpha (IL-15Rα) is a transmembrane glycoprotein that plays a pleiotropic role in immune development and function, including the positive maintenance of lymphocyte homeostasis. IL-15Rα chain can bind soluble IL-15 and “transpresent” cytokine to the cells, allowing them to respond to IL-15. Soluble IL-15Rα can function as a specific high-affinity IL-15 antagonist. The soluble IL-15/IL-15Rα complexes exhibit a strong agonistic activity which is mediated through membrane-bound IL-15 receptor β and γ heterodimers and enables signaling to cells.
description Recombinant Human Interleukin-15 receptor subunit alpha is expressed by our Mammalian expression system and the target gene encoding Ile31-Thr205 is expressed with a Fc tag at the C-terminus.
source Human Cells
AA sequence Ile31-Thr205
purity >95% as determined by reducing SDS-PAGE.
endotoxin <0.1 ng/µg (1 EU/µg) as determined by LAL test.
bioactivity Measured by its ability to block human IL-15-induced proliferation of CTLL‑2 mouse cytotoxic T cells. The ED50 for this effect is less than 10 ng/ml.
formulation Recombinant Human IL15RA Protein was lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4.
reconstitution Dissolve the lyophilized protein in distilled water.
usage For Research Use Only
storage Human IL15RA protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months.
