ELISA is a versatile and widely used technique with applications in various fields, including clinical diagnostics, immunology, and molecular biology. It provides valuable information about the presence and quantity of specific proteins or antigens in a sample, which is critical for researching, diagnosing, and monitoring various diseases and conditions. An ELISA experiment provides reproducible qualitative (Presence/Absence) and quantitative (related to specificity and sensitivity) data in a high throughput format.
