Application Functional Assays.
Background Interleukin 4 (IL-4) plays an important role in the immune response. This cytokine promotes Th2 cell development and is essential for the induction of B-cell isotype switching to IgE antibody production. This protein has an ED50 in the range 20-50 ng/ml determined by measuring the effect of recombinant equine IL-4 on the proliferation of TF-1 cells.
Storage Prior to reconstitution store at 2-8°C.
Following reconstitution store the protein undiluted at -70°C.
Avoid repeated freezing and thawing.
