Assay Development

The Key to Unlocking Promising Therapeutics

Enabling the precise and reliable measurement of drug candidate’s effects on specific biological targets

Assay development refers to the process of designing, optimizing, and validating experimental tests or assays that enable the accurate detection, quantification, or functional analysis of biological, chemical, or physical entities of interest. These assays are designed to accurately detect and quantify the activity of the drug candidate in a biological system, providing valuable information on its efficacy and potential side effects. The optimization of assays is essential to ensure that they are reliable, precise, and reproducible, enabling researchers to make informed decisions on the selection and optimization of potential drug candidates. The use of advanced technologies such as high-throughput screening (HTS) and automated platforms has greatly enhanced the efficiency and speed of assay development, allowing to screen large numbers of compounds in a relatively short period. By facilitating the rapid identification and optimization of potential drug candidates, assay development plays a critical role in the drug discovery process, ultimately leading to the development of new and effective therapies for a wide range of diseases.
