ELISA are immunoassays widely used in biomarker detection and validation. They have been used in research and clinical settings for more than 40 years, and they allow to quantify, in a simple way, thousands of biomarkers. New ELISAs are being developed every day, either for new biomarkers or new species. They can also be used to detect contaminants in food, water or industrial processes.
