IL-15R alpha is a high affinity receptor for IL-15 (Kd: 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.
