Method for direct quantification of nucleic acids in real time qPCR

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.

Off-target capture reduction in sequencing techniques

Presented herein are methods and compositions for enhancing specific enrichment of target sequences in a nucleic acid library. Off-target hybridization probes may be used to reduce binding and/or capture of off-target regions of a nucleic acid library in a targeted sequencing workflow. The off-target hybridization probes may be specific for locations known to generate off-target sequencing reads for a particular set of hybridization probes.

Double-stranded circle probes

Nucleic acid probes for detection of a target nucleic acid molecule by an RCA reaction in the presence of the target nucleic acid molecule, comprise a first circular template strand which is capable of acting as a template for RCA, and is protected from RCA in the absence of the target nucleic acid molecule by at least a second protector strand which comprises a region of complementarity to the first template strand and is hybridised thereto to form a double-stranded circular structure containing the first template strand inside the protector strand(s). At least one of the second and/or any further protector strands comprises a target binding site, such that upon binding of the probe to the target nucleic acid molecule the probe is able to undergo a strand displacement reaction which allows RCA of the first template strand. Methods of detecting target analytes use such probes.
