Product Description |
Recombinant Human IL-5 R alpha/CD125 Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains Asp21-Glu335. |
Product Background |
Interleukin‑5 Receptor alpha (IL‑5 R alpha), also known as CD125, is a 60 kDa hematopoietin receptor that plays a dominant role in eosinophil biology.This is the receptor for interleukin-5. The alpha chain binds to IL5. |
