Assay Development

Definition

Assay development is the process of creating a reliable and efficient method for measuring the biological activity, potency, or pharmacological effects of a substance, often a drug candidate. This process is crucial in drug discovery as it allows researchers to evaluate the efficacy and safety of compounds before advancing them to clinical trials. Developing assays helps in identifying lead compounds from various sources and optimizing their therapeutic potential.
