What does non specific binding mean?
Nonspecific binding is binding of the assay antibodies which is not correlated with the specificity of the antibodies. Also analytes can bind non-specifically. There are two kinds of nonspecific binding which normally occurs in the lab and which can not be distinguished from each other easily.
What is ligand binding pharmacology?
Ligand binding model is an example of a PD model that works on the underpinning PD principle of a drug, eliciting its pharmacological effect at the receptor site. The pharmacological effect is produced by the drug binding to the receptor to either activate or antagonise the receptor.
