The Enzyme-Linked Immunosorbent Assay (ELISA) is a method that relies on the specific binding between antigens and antibodies, followed by enzymatic detection, typically through a colorimetric reaction. This technique enables the direct or indirect quantification of analytes with high sensitivity and specificity. It is widely used in the diagnosis of infectious diseases, biomarker assessment, hormone testing, and cytokine assays.
This infographic provides an objective overview of the mechanisms of action, structural components, and main variants of this immunoassay based on antigen-antibody binding.
