What Is Immunometric Assay

Immunometric assays, also known as sandwich ELISAs, use two antibodies specific to the antigen to capture or “sandwich” antigens in the well for detection. Immunometric assays exhibit a direct correlation between antigen concentration and substrate response.

What does competitive assay mean?

A competitive binding assay typically measures the binding of a labeled ligand to a target protein in the presence of a second, competing but unlabeled ligand. This assay can be used to assess qualitative binding information as well as relative affinities of two or more molecules for one target.

What is immuno assay mechanism?

The Working Mechanism of Immunoassay Tests. Immunoassay tests work by using antibodies to detect small biological substances in the blood and other bodily fluids. The method follows the aspect that particular antigens binds to specific newly introduced antibodies, thereby stimulating an immune response.
