| Interleukin-15 receptor alpha (IL-15R alpha) is a high affinity IL-15 binding protein that is crucial for mediating IL-15 functions such as memory CD8 T cell proliferation and NK, NK/T cell, and intestinal intraepithelial lymphocyte development. |
| Recombinant Biotinylated Human IL-15RA/IL-15 R alpha/CD215 Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Ile31-Thr205. |
