Receptor ligand binding assay
WebbThe collective model states that the binding interaction of two proteins (here a ligand and receptor) can be described by the following equation, where L represents free ligand, R represents unbound receptor, and LR represents the bound ligand–receptor complex (Berson & Yalow, 1959; Kuriyan et al., 2013): WebbAfter inducing the receptor expression I perform the binding assay. I isolate the membranes and then add 100micrograms of protein along with 2nM of tritiated ligand to tubes along with...

WebbThe goal is to determine the Kd (ligand concentration that binds to half the receptor sites at equilibrium) and Bmax (maximum number of binding sites). Total, nonspecific and specific binding. The ligand binds not only to receptors sites, but also to nonspecific sites. There are three approaches to dealing with nonspecific binding.
