Multiplex assays have become an essential tool in modern laboratories due to their ability to analyze multiple targets simultaneously within a single experiment. Unlike traditional single-analyte tests, multiplex assays allow researchers and clinicians to detect, measure, and compare several biological markers at once, saving time, reducing sample volume, and improving overall efficiency.
At their core, multiplex assays work by combining different detection reactions into one unified platform. These reactions may involve proteins, nucleic acids, antibodies, or other biomolecules. Each target is tagged or identified using a distinct signal, such as fluorescence, colorimetric markers, or bead-based coding systems. This design enables precise differentiation between multiple analytes even when they are tested together in the same sample.
One of the most significant advantages of multiplex assays is sample conservation. In clinical diagnostics and biomedical research, sample availability is often limited. Multiplexing allows comprehensive analysis using minimal sample volumes, which is especially valuable…
