Competitive Assay Approach: Binding of Small Molecules to the Active Form of p38

November 10, 2018

p38α is considered as the key isoform involvedin modulating inflammatory response inrheumatoid arthritis and inflammatory painand is therefore a key target for compoundscreening in pharmaceutical industry. In thisstudy we demonstrate the use of MicroscaleThermophoresis to perform an essentiallylabel-free measurements of small moleculebinding to protein targets by using acompetitive approach. This approach thereforeallows screening projects aiming to identifyand characterize site-specific binders orbinders allosterically influencing a specificbinding site out of a compound library. Furthermore this approach also can be used toscreen for compounds that interrupt proteinprotein,protein-peptide or protein-nucleic acidinteractions.
