Abstract: The present invention concerns a method of determining whether a non-purified sample contains a target protein bound to a ligand of interest comprising the steps of a) exposing the non-purified sample to a temperature which is capable of causing or enhancing precipitation of the unbound target protein to a greater extent than it is capable of causing or enhancing precipitation of the target protein bound to the ligand; and b) analyzing said sample for the presence of soluble or native target protein using two or more affinity reagents capable of binding to said soluble or native target protein with a higher affinity than to an unfolded and/or insoluble form of said target protein. The invention particularly concerns the use of two affinity reagents (e.g. antibodies) which are capable of distinguishing between soluble or native, and unfolded and/or insoluble forms of a target protein and whose detection e.g. by FRET based technology, allows the performance of the method without a separation step.

Abstract: According to the invention &bgr;-tubulin, as well as a 65 kDa polypeptide present in pancreatic &bgr;-cells, have been identified as molecular targets for sulfonylurea compounds. These findings enable for the identification of new insulin secretagogues. The invention thus relates to the use of sulfonylurea compounds, such as e.g. glibenclamide, in methods for identification of compounds binding the 65 kDa polypeptide or tubulin, or stimulating tubulin polymerization and/or turnover, thereby stimulating insulin secretion.
