본 발명은 중금속에 노출된 어류체내에서 메탈로티오닌(metallothionein;MT) 유전자의 발현에 따라 MT가 증폭 생성되는 특성을 나타내므로 중금속의 양식어류 등 식용어류의 오염여부를 알아 내는데 유용한 생체지표(biomarker)로 사용될 수 있는 메탈로티오닌의 효율적인 제조방법에 관한 것이다. 본 발명에 의하면 어류의 마취 후 염화카드뮴 등 중금속 염의 고농도용액을 생리식염수에 녹여 주사한 후 적절한 위생관리를 통하여 어류가 폐사되지 않도록 하여 메탈로티오닌의 고농도 유도가 용이하게 이루어지도록 하고, 아울러 유도기간 중 어류체내에 유도된 메탈로티오닌을 회수하는 데에 있어서도 복잡한 해부과정을 거쳐 간(liver)과 아가미(gill) 등의 장기와 기관의 적출 및 이에 수반되는 균질화 추출과정을 거치지 않고 혈액을 채취하여 회수된 어류의 혈액내로 유도된 메탈로티오닌을 어류의 혈청으로부터 간편한 음이온교환 크로마토그래피 과정을 통하여 어종별 메탈로티오닌 항체제작 및 분석용 표준품으로서 사용가능할 정도로 간편하게 정제할 수 있다. 따라서 본 발명에서 제시한 메탈로티오닌의 효율적 제조방법은 양식어류 등 식용어류의 중금속 오염여부에 대한 생체지표 검색기술 개발에 필수적인 원천기반기술의 하나로서, 이 방법에 따른 산물로서 생산되는 어류 메탈로티오닌의 활용을 통하여 중금속오염 생체지표에 대한 면역센서와 효소면역분석법 등의 분석법 개발이 촉진되어질 수 있을 것으로 기대된다. 중금속오염, 생체지표, 메탈로티오닌, 식용어류
