Interleukin-4 Recombinant Protein has been tested by biological activity and is suitable as a control for polyclonal or monoclonal anti-Interleukin-4 in immunological assays.
Bioactivity of Mouse Interleukin-4 Recombinant Protein. MC-9 cells were cultured with 0 to 2 ng/mL Mouse IL-4. Cell proliferation was measured and the linear portion of the curve was us used to calculate the ED50. The ED50 of Mouse IL-4 is 0.016-0.046 ng/mL. This value is comparable to expected range of less than 0.2 ng/mL.
