Constituent 1
In chemico test system
- Details on the study design:
- The Direct Peptide Reactivity Assay (DPRA) was used to assess the skin sensitizing potential of the test article. Synthetic peptides containing cysteine or lysine were reacted with the test article for 24± 2 hours. After the incubation period, the extent of peptide depletion was analyzed using High Performance Liquid Chromatography (HPLC) coupled with ultra-violet (UV) spectrometric detection.
The purpose of this study was to determine the percent of peptide depletion of the test article treated peptides compared to the controls. The laboratory phase of the study was conducted from 18 April 2018 to 27 April 2018 at the Institute for In Vitro Sciences, Inc. The test article was tested in at least one valid definitive assay to determine the reactivity classification for the test article based on the percent depletion of the peptide caused by the test article.
