Transgenic medaka is designed for testing Estrogenic Endocrine Disruptors (EEDs), a major group of harmful substances. It can be used to test everyday consumer products (including food, pharmaceuticals and cosmetics), and monitor the aquatic environment. Transgenic medaka fish assay is so far the most accurate and cost-effective method to detect Estrogenic Endocrine Disruptors (EEDs). When the fish detect EEDs, it will produce green fluorescence (see the picture on the right), and then the intensity of the light is used to quantify the EEDs. By applying this technology in the screening stage of the testing process, 60% of the time and money can be saved, while it can also detect unknown substances belonging to the group of EEDs.
