August 21, 2016The Normal Human Epidermal Keratinocytes (NHEKs) Cytotoxicity Assay using a Neutral Red Uptake (NRU) viability endpoint is a 96-well cytotoxicity assay to assess the toxicity potential of a test material. The assay utilizes primary NHEK cells and may be used to predict either human lethal serum concentrations or in vivo rodent LD50 starting doses for acute oral systemic toxicity. Cytotoxicity caused by the test article is measured by a concentration-dependent reduction in neutral red uptake (NRU) by the cells after exposure to a...
