Cytotoxicity assays are crucial for several reasons:
1. Drug Development: They help in screening and identifying the toxicity of new pharmaceutical compounds. 2. Environmental Safety: These assays are used to evaluate the toxicity of pollutants and chemicals in the environment. 3. Regulatory Compliance: Regulatory agencies require cytotoxicity data for the approval of new chemicals and drugs. 4. Mechanistic Studies: They provide insights into the mechanisms of toxicity at the cellular level.
