  • Patent number: 11603561
    Abstract: A method for direct quantification of nucleic acids in real time qPCR. The invention discloses a method for specific quantification of nucleic acids in real time qPCR. The disclosed invention can be achieved in three ways; 1) using a modified primer for qPCR quantification; 2) using strand displacement based probes for qPCR quantification; 3) using label-free endonuclease probe for qPCR quantification. The mechanism of quantification is based on the fact that, DNA, RNA or modified oligonucleotide based light-up dye-aptamer system, where dye is not fluorescent in free state but its fluorescence increases multi-fold when it binds to its specific aptamer.
