Chromatography-based assays, such as gas chromatography (GC) and high-performance liquid chromatography (HPLC), play a significant role in the pharmaceutical industry. These methods provide high-resolution separation of complex mixtures. GC is commonly used for volatile compounds detection, while HPLC is suited for non-volatile and thermolabile molecules. An advantage of using these techniques is their ability to analyze compounds in low concentrations, which is invaluable in pharmacokinetics studies to determine drug absorption, distribution, metabolism, and excretion (ADME) in the body.

When selecting an assay method, consider the type of sample, the specificity required, and the sensitivity needed for accurate results.

What is an Assay in Biotechnology

Assays in biotechnology refer to any experimental procedure that quantitatively or qualitatively measures the presence, amount, or activity of a target entity, such as a protein, enzyme, or nucleic acid in a sample. These assays are fundamental to understanding complex biological systems and optimizing product development.

An assay is a test or analysis, especially one that determines the presence or quantity of a particular substance using biological tools.

Assays can be classified based on different parameters, including:

Quantitative vs. Qualitative: Quantitative assays measure the precise amount of a target, while qualitative assays confirm the presence.
In vitro vs. In vivo: In vitro assays are performed in controlled environments outside living organisms, whereas in vivo assays are conducted within living cells or organisms.
Functional vs. Non-functional: Functional assays assess biological activity, whereas non-functional assays measure the amount of the analyte without assessing activity.

The choice of assay depends on the specific objectives of the research or industrial process.

An example of a functional assay in biotechnology is the luciferase reporter assay, which is used to measure cell signaling pathways by detecting light emission as a readout of gene expression activity.
