Video: The 3T3 Neutral Red Uptake Phototoxicity Test

October 31, 2018
This training video explores a cell-based method for assessing Phototoxicity — or the potential for chemicals to cause damage after being exposed to light.  The method is used widely around the world by many industries, including the cosmetics and pharmaceutical sectors. Disclaimer:  Please note that the procedures shown in this video were for demonstration purposes only and that all assay procedures, except the UV A/dark exposure, should be performed in a biological safety cabinet using aseptic techniques. Due to video production reasons,...

The Assessment of Phototoxicity Using the 3T3 Neutral Red Uptake (NRU) Phototoxicity Assay and a Modified Photo-Direct Peptide Reactivity Assay (DPRA)

March 28, 2018
Alternative methods, including the validated 3T3 Neutral Red Uptake (NRU) Phototoxicity assay (OECD TG 432) may be used as a pre-clinical test to address phototoxicity. Currently, there are no validated alternative test methods to identify photoallergens; however, there are several validated alternative test methods to address skin sensitization, including the Direct Peptide Reactivity Assay (DPRA) (OECD 442C). To address photoallergy, we utilized the 3T3 Phototoxicity assay in combination with a modified photo-DPRA assay to determine if these assays were able...
