Immunoassay systems are specialized analytical platforms designed for the detection and quantification of biomolecules, such as proteins, hormones, antigens, and antibodies. These systems are essential tools in clinical diagnostics, biomarker discovery, infectious disease testing, vaccine development, and drug screening. Immunoassays rely on the high specificity of antibody-antigen interactions to detect target analytes in complex biological samples like blood, serum, plasma, or tissue lysates.
Among the most widely used types of immunoassays is the enzyme-linked immunosorbent assay (ELISA), which offers high sensitivity and throughput for quantifying target molecules. ELISA platforms can be formatted as direct, indirect, sandwich, or competitive assays, depending on the assay goals and the type of analyte being measured. These systems are used in workflows such as cytokine profiling, autoimmune disease screening, allergy testing, and therapeutic drug monitoring.
ELISA readers, also known as microplate readers or absorbance readers, are a key component of immunoassay workflows. They detect and quantify colorimetric changes resulting from enzyme-substrate reactions in 96- or 384-well plates. These changes correlate directly with analyte concentration, allowing for accurate and reproducible results. Advanced ELISA readers may also support fluorescence, luminescence, and multiplex detection, making them versatile for expanding assay capabilities.
Modern immunoassay systems often include features such as automated plate handling, incubation control, washing stations, and integrated software for data analysis and report generation. These systems reduce hands-on time and enhance throughput, making them ideal for high-volume testing environments.
