A ligand binding assay (LBA) is an assay, or an analytic procedure, which relies on the binding of ligand molecules to receptors, antibodies or other macromolecules. A detection method is used to determine the presence and extent of the ligand-receptor complexes formed, and this is usually determined electrochemically or through a fluorescence detection method. This type of analytic test can be used to test for the presence of target molecules in a sample that are known to bind to th… WebTraductions en contexte de "ligand-binding assays" en anglais-français avec Reverso Context : ELISA stands for enzyme-linked immunosorbent assay and is a widely used biochemical analysis technique of the category of ligand-binding assays.
