IL-5 R alpha/CD125: ELISA Kits

As is the case with many other cytokines, the functional high-affinity receptor for IL-5 is a complex consisting of a ligand binding subunit (alpha chain) and a second subunit (beta chain) that can modulate the ligand binding affinity of the receptor complex. In the case of IL-5, the beta subunit is shared with the high affinity receptor complexes for IL-3 and GM-CSF and is called the common beta chain.
