Sensitivity of the multiplex EPFS assay for GM maize detection. Multiplex EPFS assay were performed on a series of DNA solution with a final relative content of 10%, 5%, 1%, 0.5% and 0.1% (w/w). The column with slash means negative, which was lower than the threshold. FAM: labeled BT176 amplicons; HEX: labeled GA21 amplicons; ROX: labeled NK603 amplicons; NED: labeled TC1507 amplicons; RFU: relative fluorescence units.
