WebThe TOP assay is an analysis by difference approach, where two aliquots of a sample are analyzed. One aliquot is pre-treatment and the other is post-treatment, with the latter subjected to strong oxidizing conditions prior to PFAS analysis. The PFAS concentration difference between the pre- and post-treatment samples is defined as the amount of ... WebTOPFlash/FOPFlash assays. TOPFlash is a luciferase reporter that contains a minimal fos promoter coupled to Tcf-binding sites upstream of a modified firefly luciferase gene. FOPFlash is similar, except that the Tcf-binding sites are mutated and non-functional. Thus, FOPFlash, which is a control reporter, yields expression from the
