WebA published peptide depletion assay was used to relate the in vitro reactivity of fragrance molecules to LLNA data. Using the classical assay, 22 of 28 tested moderate to strong sensitizers were positive. The prediction of weak sensitizers proved to be more difficult with only 50% of weak sensitizers giving a positive response, but for some ... WebAbstract.

USP (87) Biological Reactivity Tests, In Vitro (Cytotoxicity)
WebThe biological reactivity of the cells exposed to the sample or sample extracts is rated on a scale of 0-4 (see Table 1 below). The biological reactivity is determined by assessing the nonlethal injury of the cells (cellular degeneration) and any structural defects (malformations) the cells have. WebThe in vitro irritation testing starts with the preparation of polar as well as non-polar medical device extracts according to ISO 10993-12. Afterward, each extract is exposed to the tissue, just by topical application, and incubated. Finally, the tissue is rinsed and exposed to MTT. WebFeb 23, 2024 · Contact FDA. 301-796-5450.
