IL-15R alpha is a high affinity receptor for IL-15 (K d : 100 pM). IL-15 is essential for the development and function natural killer (NK) cell, NKT cell and memory (m) CD8+ T cell [1] . IL-15R alpha maintains memory CD8+ T cell homeostasis and lymphocyte development. IL-15R alpha/IL-15 complex can activate the antitumor functions of NK cells and CD8+ T cells [2] [3] . IL-15R alpha & IL-15 Protein, Human (HEK293, His) is a recombinant human IL-15R alpha (I31-S108) & IL-15 (N49-S162) fusion protein with a C-Terminal His tag, which is produced in HEK293 cells.

Human

IL-15R alpha is expressed on various cell types, including lymphocytes, myeloid cells, nonlymphoid and nonhematopoietic cells [4] . IL-15 is produced in macrophages and dendritic cells [1] . IL-15R alpha is required for transporting of IL-15 from the endoplasmic reticulum to the cell surface to bind with β (CD122) and γ (CD132) chains on responding lymphocytes [4] [5] . When binding with IL-15, the complex increases the in vivo half-life of IL-15 and enhances binding affinity of IL-15 with IL-15Rβ/γ in NK cells and CD8+ T cells. Thus, the signal transmission improves proliferation and antitumor activities of NK cells and CD8+ T cells [2] . IL-15R alpha forms complex with IL-15 and activates the antitumor functions of NK cells and CD8+ T cells. IL-15R alpha/IL-15 complex is a potential immunotherapeutic agent for cancer and viral infection [1] .
