Radioligand Binding Assays

Radioligand binding assays are used to characterize the binding of a drug to its target receptor. They can provide information on both the affinity and mode of interaction of the drug with its receptor.

One way the immune system attacks foreign substances in the body is by making large numbers of antibodies. An antibody is a protein that sticks to a specific protein called an antigen. Antibodies circulate throughout the body until they find and attach to the antigen. Once attached, they can recruit other parts of the immune system to destroy the cells containing the antigen.

Autoradiography can be used to determine anatomical distribution of binding sites of a radiolabeled drug (receptor distribution), receptor occupancy of a competing unlabeled drug given either in vitro or ex vivo & biodistribution of radiolabeled drug among the organs.
