IL-15R alpha, Human (Biotinylated, HEK293, His-Avi)

IL-15R alpha is a high affinity receptor for IL-15 (Kd: 100 pM)[1]. IL-15R alpha binds IL-15 and thereby activating the antitumor functions of NK cells and CD8+ T cells[2]. IL-15R alpha plays an important role in memory CD8+ T cell homeostasis and lymphocyte development[3]. IL-15R alpha Protein, Human (Biotinylated, HEK293, His-Avi) is a biotinylated recombinant human extracellular region of IL-15R alpha (I31-T205) with a C-Terminal His-Avi tag, which is produced in HEK293 cells.
