OECD 439: In vitro skin irritation (EpiSkin™ / EpiDerm™)

Study

Toxicology, In Vitro Alternate

Skin irritation tests are performed using in vitro 3D human skin tissue models that closely mimic the human epidermis, such as EpiDerm™ and Episkin™ models which consist of human epidermal keratinocytes. Irritant chemicals are identified by their ability to decrease cell viability below defined threshold levels. Cell viability is measured by enzymatic conversion of the vital dye MTT into a blue formazan salt that is quantitatively measured. Colored chemicals can also be assessed using high-performance liquid chromatography (HPLC).

About our nonclinical animal research models: We provide the utmost care for our research animals and actively pursue advances in animal welfare. As well as ensuring the highest scientific, ethical and regulatory standards, selection of appropriate animal research models for development research is critical to developing safe and effective treatments, devices and products that protect and save lives. Just as we have ethical committee oversight for human trials, we have ethical committees overseeing all aspects of our global animal care and use programs. All of our core, nonclinical facilities are accredited by AAALAC. Learn more about our commitment to replacing, reusing and refining nonclinical research models.
