Heat shock protein 70 levels in rainbow trout primary epidermal cultures in response to 2,4‐dichloroaniline exposure: A novel in vitro aquatic toxicity marker

The aim of this work was to investigate the use of the heat shock protein, HSP 70, as a sublethal measurement of ecotoxicity and to identify if the amount of HSP 70 synthesized is proportional to the chemical stress applied. This was achieved by quantifying the HSP 70 levels in primary cultured rainbow trout, Oncorhynchus mykiss (R.), skin epidermal cells in response to 2,4-dichloroaniline (2,4-DCA) exposure. The cellular stress response …
