Metallothionein (MT) is known to be involved in various physiological roles and diseases. However, a standard method for MT measurement has not been established until recently. Therefore, we have developed an easy and specific enzyme-linked immunosorbent assays (ELISA) to determine MT-1 and MT-2. In order to evaluate the method we developed, MT-1/2 in liver, kidney and brain was determined in wild type (WT), MT-1/2 knockout (KO) and MT-3 KO mice, with and without Cd treatment. MT 1/2 in urine was determined in genetically disordered LEC rats (an animal model of Wilson disease). MT-1/2 concentrations in the liver, kidney and brain in MT-1/2 KO mice were significantly lower compared to those of WT and MT-3 KO mice. MT-1/2 concentrations in the livers of WT mice significantly increased with Cd administration, but not in MT-1/2 KO mice. Similar results were observed by immunohistochemical staining. To confirm the molecular weight (MW) of MT detected in organs by the ELISA, analysis with a Sephadex G-75 was performed. Two peaks of MT-1/2 (MW small and large) were detected in WT and MT-3 KO mice. The small MT peak was mostly depleted in MT 1/2-KO mice, while a large MT peak remained. A significant increase in MT-1/2 concentration was detected in the urine of LEC rats with age and especially at the hepatitis stage. In conclusion, MT-1/2 ELISA and immunohistochemical staining was highly correlated with MT-1/2 determination in experimental animal specimens and could be a robust analytical tool for physiological and toxicological studies.
