Nettet13. okt. 2024 · The aim of binding assays is to measure interactions between two molecules, such as a protein binding another protein, a small molecule, or a nucleic acid. Hard work is required to prepare reagents, but flaws in the design of many binding experiments limit the information obtained. In particular many experiments fail to … Nettetfrom ligand and receptor total concentrations, depending on the corresponding dissociation constant. This model was validated using data of Bodipy-NDP-αMSH binding to MC 5, obtained after either ligand saturation of a receptor preparation or, conversely, receptor saturation of a ligand solution.
NettetIn a saturation binding experiment, you vary the concentration of radioligand and measure binding. The goal is to determine the Kd (ligand concentration that binds to half the receptor sites at equilibrium) and Bmax (maximum number of binding sites). The ligand binds not only to receptors sites, but also to nonspecific sites. Nettet6. mai 2003 · The observed stability of a protein is altered when ligands bind, ...
