  • Patent number: 10669573
    Abstract: The invention relates to a method for confirming an amplified nucleic acid target sequence (target sequence), preferably from human samples, during a multiplication reaction in a collective and continuous reaction batch as a one-pot process, wherein the confirmation of the target sequence amplification product is obtained by means of a hapten-pair-marked artificial template amplification product. The artificial template sequence is amplified and optionally marked by means of the 5?-cleavage products of the at least one target-sequence-specific FEN probe. The 5?-cleavage product of the at least one target-sequence-specific FEN probe is obtained only if the FEN probe hybridizes, by means of the target-sequence-specific 3? sequence thereof, to a complementary sequence segment of the at least one target sequence. The detection of the obtained plurality of template amplification products occurs distinctly and preferably by means of immunochromatographic methods.

  • Patent number: 8962820
    Abstract: The present invention relates to combinations of fluorescent dyes used in molecular biology, particularly in multiplex PCR. In particular, the present invention relates to a combination of dyes for amplification reactions, wherein at least four different dyes are used, wherein the first dye is 5-FAM or 6-FAM or a blend thereof, the second dye is selected from the group consisting of DY-530, HEX, CAL Fluor Orange 560 and ATTO 532, the third dye is selected from the group consisting of ATTO 550, DY-555 and DY-556, the fourth dye is selected from the group consisting of ROX, DY-510XL and ATTO 565, and optionally a fifth dye is selected from the group consisting of DY 632 and DY-520XL.
