Scope
This document describes the method for testing the thyroid activity of African clawed frog embryos. This document is suitable for screening the response of African clawed frog embryos to potential thyroid active substances; it is suitable for screening potential thyroid active substances. This document is not suitable for volatile chemical substances; it is not suitable for chemical substances that accumulate in African clawed frog embryos and emit fluorescence in the wavelength range of 500 nm to 550 nm when excited by wavelengths in the range of 450 nm to 500 nm.
