HTS (High-Throughput Screening)
HTS (high-throughput screening) aims to rapidly analyze and evaluate the biological activity or characteristics of large numbers of compounds, proteins, or other biomolecules. Central to this method is the use of automated equipment and miniaturization technologies, which enable rapid, systematic analysis of extensive sample sets to identify potentially bioactive compounds, antibodies, or genes. The applications of HTS span a broad range of fields, from drug discovery to fundamental biological research, providing researchers with comprehensive datasets and valuable insights. In drug discovery, HTS is especially valuable because traditional screening methods are laborious and time-consuming, whereas HTS technologies can rapidly screen compound libraries containing tens of thousands of molecules, identifying candidates with specific affinity for target proteins or receptors. Consequently, HTS greatly accelerates early-stage drug discovery, offering researchers a powerful tool for efficiently identifying compounds with therapeutic potential. In genomics, HTS facilitates the large-scale functional analysis of genes; researchers employing RNA interference or CRISPR-based screens can swiftly identify key genes and elucidate their roles in biological processes. In metabolomics, HTS supports the evaluation of relative abundances and dynamic variations among numerous metabolites, thereby advancing our understanding of metabolic pathway dynamics. Furthermore, HTS is extensively applied in agriculture, cosmetics, and food safety sectors. For example, in agriculture, it is used to identify plant-derived compounds capable of enhancing disease resistance or increasing crop yields; in food safety, HTS enables rapid detection of harmful contaminants in food products, enhancing detection efficiency and accuracy.
The workflow of HTS (high-throughput screening) typically begins with the preparation of a large chemical library containing tens of thousands of diverse compounds. These compounds are usually stored in small quantities suitable for testing in microplate formats. Subsequently, researchers select an appropriate biological target, such as an enzyme, receptor, or ion channel, and develop a corresponding screening model. This model must accurately replicate interactions between compounds and the target. With automation support, compounds are dispensed into the model system, initiating the screening process. Throughout the entire HTS workflow, automated systems equipped with high-precision robotic arms and optical detection technologies ensure accurate execution of each experimental step and precise data acquisition. Data analysis software then processes and interprets the collected data to identify bioactive candidates.
Nevertheless, HTS (high-throughput screening) technology has certain limitations. One prominent issue is the potential for high rates of false-positive and false-negative results, largely due to minor variations in experimental conditions that are challenging to control uniformly at high throughput. Moreover, HTS commonly utilizes simplified biological models that may not fully represent the complexity of actual biological systems, potentially affecting result reliability. Thus, subsequent validation experiments are crucial to confirm compound bioactivity in physiologically relevant contexts. Additionally, HTS demands considerable initial investment, including expensive instrumentation, extensive chemical libraries, and highly trained technical staff.
