Binding competition assay
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 … See more Historically, ligand binding assay techniques were used extensively to quantify hormone or hormone receptor concentrations in plasma or in tissue. The ligand-binding assay methodology quantified the … See more Radioligands are used to measure the ligand binding to receptors and should ideally have high affinity, low non-specific binding, high specific activity to detect low receptor densities, … See more Immunoprecipitation The liquid phase ligand binding assay of Immunoprecipitation (IP) is a method that is used to purify or enrich a specific protein, or a group of proteins, using an antibody from a complex mixture.
