Bioactivity

1. Immobilized human IL4R-His at 10 μg/mL (100 μl/well) can bind biotinylated human IL4. The EC50 of biotinylated human IL4 is 20.8-48.5 ng/mL. 2. Measured by its ability to inhibit IL-4 dependent proliferation of TF-1 human erthroleukemic cells. The ED50 for this effect is 4-20 ng/ml in the presence of 2 ng/ml IL-4.
