    摘要: An object of the present invention is to provide a process for producing 2-(4-pyridyl)ethanethiol easily. According to the invention, 4-vinylpyridine is reacted with thiourea in an aqueous medium containing an acid to form a solution containing an isothiuronium salt and then the solution is made alkaline to convert the isothiuronium salt into 2-(4-pyridyl)ethanethiol.

    摘要: A substrate comprises a surface, and a plurality of moieties, on at least a portion of the surface. The moieties are moieties of formula:Surf-LnullQnullT,where nullT comprises a reactant ligand, and Surf- designates where the moiety attaches to the surface. The substrate can be made into a protein chip by the reaction of a reactant ligand and a fusion polypeptide, where the fusion polypeptide includes a capture polypeptide moiety which corresponds to the reactant ligand.
