In Vitro Assays

In vitro assays are experimental procedures performed in a controlled environment outside a living organism. These assays are crucial for testing drug effects on isolated cells.

Assay: A laboratory procedure for measuring the presence, amount, or activity of a particular substance.

One common in vitro assay involves testing the cytotoxicity of a new drug by observing its effect on cultured cancer cells.

Receptor Binding Studies

Receptor binding studies are used to understand the interaction between a drug and its target receptor on a cell. These studies help determine:
