1 From publication date to the end of 2018. 2 Possibly overestimated due to widespread usage of TEAC abbreviation for AOA/AOC results expression in different assays. 3 Words “rapamycin”, “photobleaching”, and “phosphatase” were excluded from this search to prevent overestimation due to other FRAP abbreviations not related to antioxidant activity assessment (i.e., fujimycin binding protein (FKBP)-rapamycin-associated protein, fluorescence recovery after photobleaching, and fluoride-resistant acid phosphatase).
