What is assay development?
Assay development in molecular biology is a critical, multi-step process involving the identification and validation of drug targets, creation of biochemical and cell-based assays—such as kinase activity and cell proliferation tests—to measure drug activity, safety, and efficacy, with careful consideration of factors like relevance, reproducibility, quality, interference, and cost to ensure successful drug discovery and development.
Assay development is a procedure employed in molecular biology to test or measure the activity of a drug in an organism. Assays are investigative procedures that qualitatively assess a compound or examine its effect on a molecular target. The development of successful assays is critical in drug discovery and development, with better assays increasing confidence in the productive and successful realization of new drugs.
Developing functional assays requires a thorough consideration of many factors, including:
- Relevance
- Reproducibility
- Quality
- Interference
- Cost
Assay development examples
The first stage of drug development involves the identification and verification of prospective targets associated with human diseases. Some examples of these targets include:
- Receptors
- Enzymes
- DNA
- Hormones and factors
- Ion channels
There are many examples of various categories of assays, including biochemical assays and cell-based assays. Some examples from both categories include:
- ADP Hunter Assay for Kinase Activity
- Cell Proliferation Assays
- Assay for Protease Cleavage Activity
- Migrations Assays
- Reporter Gene Assays
How to develop an assay
There are several steps of assay development:
- Step 1: Identification and validation of drug targets
- Step 2: Biological assays and compound screening assays are produced
- Step 3: Cell-based assays are used to examine a drug’s safety and efficacy
Drug development always involves undergoing numerous assays that are tailored for the specific drug target and compound.
