Product Description |
Recombinant Human IL-15RA&IL-15 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Ile31-Ser108(IL-15RA)&Asn49-Ser162(IL-15). |
Product Background |
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. |
