immunoassays

**immunoassays**

Immunoassays are laboratory techniques used to detect or quantify specific proteins, hormones, or other molecules through the use of antibodies. Widely applied in medical diagnostics, research, and drug development, immunoassays leverage the specificity of antigen-antibody interactions to measure substances such as biomarkers, pathogens, or drugs in complex samples. Common types include ELISA, radioimmunoassay, and Western blot, each offering unique advantages depending on sensitivity, specificity, and application needs. This tag covers topics related to the principles, methods, and applications of immunoassays in various scientific and clinical settings.
