Bioactivity

1. Using the Octet RED System, the affinity constant (Kd) of Human IL2RA-his bound to Human IL2 was 35nM. 2. Measured by its ability to inhibit IL2-dependent proliferation of MO7e human megakaryocytic leukemic cells in the presence of 30 ng/mL of recombinant human IL-2. The ED50 for this effect is 0.15-0.75μg/mL.
