摘要：

In order to develop a stain with increased sensitivity and selectivity for cadmium (Cd), we synthesized and characterized 2-(8-quinolylazo)-4,5-diphenylimidazole (QAI). This chelating agent was more than twice as sensitive for Cd than the best conventional staining agents, including benzothiazolylazo-beta-naphthol. Differentiation between Cd and zinc (Zn) was achieved by immersing tissue sections in TRIS(2-aminoethyl)amine before they were stained with QAI. This pretreatment made it possible to selectively stain for Cd by blocking Zn.
