The RTgill-W1 cell line assay describes a 24-well plate format fish cell line acute toxicity test using the permanent cell line from rainbow trout (Oncorhynchus mykiss) gill, RTgill-W1. After 24 h of exposure to the test chemical, cell viability is assessed based on three fluorescent cell viability indicator dyes, measured on the same set of cells. Resazurin enters the cells in its non-fluorescent form and is converted to the fluorescent product, resorufin, by mitochondrial, microsomal or cytoplasmic oxidoreductases.

The EASZY assay is a mechanism-based in vivo screening assay designed to detect endocrine active chemicals acting as agonist through estrogen receptors (ERs), by inducing the expression of the green fluorescent protein (GFP) driven by the cyp19a1b promoter. The EASZY assay allows for the detection of estrogenic activity of chemicals on transgenic tg(cyp19a1b:GFP) Zebrafish embryos exposed for 96 hours during the embryonic stages of development.
