Tox21 employs a variety of modern techniques to accomplish its goals:
High-Throughput Screening (HTS): This technique allows for the rapid testing of thousands of chemicals across a multitude of biological assays. Computational Toxicology: Computational models are used to predict the potential toxicity of chemical substances based on their molecular structure and other properties. In Vitro Testing: Laboratory-based assays that use cells or biological molecules to evaluate the toxicity of chemicals.
