Executive Industry Relevance

Quantitative mapping of aptamer-small molecule binding sites using MicroScale Thermophoresis (MST) addresses a critical need for precise target validation and mechanistic de-risking in early discovery. MST's sensitivity and independence from molecular size enable robust characterization of challenging interactions, supporting predictive confidence at key portfolio inflection points. This capability enhances the reliability of molecular interaction data for downstream screening and lead identification.
