Researchers at a drug company conducting a cytotoxicity assay on potential novel drugs. The tests are carried out to evaluate the cellular toxicity of compounds that have demonstrated pharmacological activity in screening tests. Different amounts of the novel compounds are added to the culture wells and cytotoxicity is determined by colorimetry. A high colour intensity corresponds to low toxicity. In this version the researchers are wearing face masks. G350/188 is similar, but no masks are being worn.
