Multiplex detection refers to the simultaneous detection of multiple analytes (such as proteins, nucleic acids, or small molecules) in a single sample. This approach allows for the efficient and high-throughput analysis of multiple targets, saving time, sample volume, and reagents compared to traditional single-analyte assays. Multiplex detection is commonly used in fields such as diagnostics, proteomics, genomics, and drug discovery, where the ability to analyze multiple analytes at once is essential for understanding complex biological systems and identifying biomarkers. Various technologies, such as microarrays, bead-based assays, and mass spectrometry, are used for multiplex detection, each offering unique advantages and applications.
