    摘要: The present invention provides a method of rapidly screening ligands on the basis of their binding affinity and binding enthalpy by carrying out binding assays at a minimum of two temperatures. This technique permits the selection for further optimization of lead ligands that bind to the target molecules with favorable enthalpies. Those ligands will exhibit higher solubilities in aqueous solution than ligands selected by conventional means, and may exhibit lower susceptibilities to resistant mutations. The method may be utilized as a standalone technique, or may be adapted to, for example, known high throughput screening technologies. The present invention further comprises an apparatus for carrying out the described methods.

    摘要: A method for identifying a ligand or compound which binds to albumin comprises the steps of contacting a reaction mixture comprising a site-specific probe and albumin in the presence and the absence of the ligand or compound and measuring either dissociation constant KD, inhibitor concentration IC50 or fluorescence displacement; whereby a change in KD, IC50 and/or fluorescence in the presence of the ligand or compound is indicative of the ligand or compound binds to albumin.
