Supplier Page from Biorbyt for Human IL4R protein
Application Notes: Extracellular Domain
Biological Activity: ①The ED50 as determined by its ability to inhibit IL-4-dependent proliferation of TF‑1 human erythroleukemic cells is 5-20 ng/ml.②Measured by its binding ability in a functional ELISA. Immobilized Human IL-4 RA-Fc at 5µg/ml can bind Human IL-4 (Biotinylated by NHS-biotin prior to testing), the ED50 of Human IL-4 is 2.43 ng/ml.
Biological Origin: Homo sapiens (Human)
