We have developed luciferase reporter bioassays which individually can be used for the quantitation of a variety of cytokines and growth factors including IL-2, IL-6, IL-7, IL-10, IL-12, IL15, IL-17, IL-22, IL-23, TNFα, TGFβ, BCMA, TPO, VEGF, and RANKL using respective mechanism of action pathways. The bioassay format is based on thaw-and-use cells, eliminating the need to establish and preculture cytokine responsive cell lines which provides the benefits of convenience, reproducibility, and transferability. We demonstrate these assays measure cytokine response and inhibition with blocking drugs or potency changes from stressed samples. In summary, these reporterbased bioassays provide valuable tools for the development, stability testing, and potency determination in the manufacture of cytokine biosimilars and biobetters.
