For example, In vivo biological research differentiates whole organism research from in vitro research, which is performed on organs, tissues, cells, cellular components, proteins, or biomolecules. Clinical trials are a form of in vivo research, albeit on humans. In silico research refers to numerical simulation on a computer of, for example, a reaction between two proteins.

The in vivo-in vitro dichotomy is also frequently used in a medical context, e. g. in vivo-in vitro fertilization.
