I don't know much about toxicity, but it seems to me that "toxicity"
means that the cell should get sick, and possibly die. Your proposed
approach seems to assume that changes in cytokines is the same as
"toxicity". Is that actually true? Why not just measure whether cells
get sick and die (e.g., using a stain for living vs dead cells)?
