Structure-Guided Discovery of High-Affinity Methotrexate Aptamers for Electrochemical Drug Monitoring

Methotrexate (MTX) is a narrow-therapeutic-index drug widely used in cancer and autoimmune disease treatment, for which delayed clearance can cause severe toxicity and requires close therapeutic drug monitoring. Here, we integrate high-stringency Capture-SELEX, biophysical characterization, molecular modeling, mutation...

Conformation-Selective Binding Domains of Intramolecular Chemically Induced Protein Dimerisation Systems.

It is demonstrated that CID systems can be used as building blocks for higher-order ligand-controlled protein systems and established a generalisable strategy for harnessing the affinity gains of intramolecular CID systems to create gain-of-signal assays for small molecules and ions.
