Protein Binding Assays: Technology Overview and Market Insights

Protein binding assays are analytical techniques used to measure the binding affinity of a protein to a ligand. These assays are widely used in drug discovery and development, as they provide critical information about the interaction between a drug candidate and its target protein. In this article, we will provide an overview of protein binding assays, key players in the market, market challenges, opportunities, and the future of this technology.

Overview

Protein binding assays can be classified into two categories: equilibrium binding assays and kinetic binding assays. Equilibrium binding assays measure the binding affinity of a protein to a ligand at a steady state, while kinetic binding assays measure the rate of binding and dissociation of a protein-ligand complex. Both types of assays can be performed using various technologies, including surface plasmon resonance (SPR), isothermal titration calorimetry (ITC), fluorescence polarization (FP), and radioligand binding assays.

SPR is a label-free technology that measures changes in the refractive index of a surface as a protein-ligand complex forms. ITC measures the heat released or absorbed during a binding event, while FP measures changes in the polarization of fluorescent molecules as they bind to a protein. Radioligand binding assays use radioactive isotopes to label ligands and measure their binding to proteins.

Protein binding assays are used in various applications, including drug discovery, pharmacokinetics, and toxicology. In drug discovery, protein binding assays are used to identify and optimize drug candidates with high binding affinity to their target proteins. In pharmacokinetics, protein binding assays are used to determine the fraction of a drug that is bound to plasma proteins, which affects its distribution and elimination from the body. In toxicology, protein binding assays are used to assess the potential toxicity of drugs by measuring their binding to off-target proteins.
