Storage Lyophilized protein should be stored at < -20°C, thoμgh 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.
Reconstitution Dissolve the lyophilized protein in distilled water.
Purity Greater than 95% as determined by reducing SDS-PAGE.
Endotoxin Less than 0.1 ng/μg (1 EU/μg) as determined by LAL test.
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 throμgh membrane-bound IL-15 receptor β and γ heterodimers and enables signaling to cells.
Biological_Activity Measured by its ability to block human IL-15-induced proliferation of CTLL 2 mouse cytotoxic T cells. The ED50 for this effect is 0.35-3.5 ng/ml.
