Abstract: The present disclosure relates to methods of identifying target nucleic acids by using coded molecules and its analysis by translocation through a nanopore. Generally, coded molecules are subject to a target polynucleotide dependent modification. The modified coded molecule is detected by isolating the modified coded molecules from the unmodified coded molecules prior to analysis through the nanopore or by detecting a change in the signal pattern of the coded molecule when analyzed through the nanopore.

Abstract: A system and method are described for electroporating a sample that utilizes one or more sets of electrodes that are spaced apart in order to hold a surface tension constrained sample between the electrodes. The first electrode is connected to the lower body of the system while the second electrode is connected to the upper body. Both electrodes are connected to a pulse generator. Each electrode has a sample contact surface such that the first electrode and the second electrode may be positioned to hold a surface tension constrained sample between the two sample contact surfaces and the sample may receive a selected electric pulse.

Abstract: The present invention is directed to methods, reagents, kits, and compositions for identifying and quantifying target polynucleotide sequences. A linker probe comprising a 3? target specific portion, a loop, and a stem is hybridized to a target polynucleotide and extended to form a reaction product that includes a reverse primer portion and the stem nucleotides. A detector probe, a specific forward primer, and a reverse primer can be employed in an amplification reaction wherein the detector probe can detect the amplified target polynucleotide based on the stem nucleotides introduced by the linker probe. In some embodiments a plurality of short miRNAs are queried with a plurality of linker probes, wherein the linker probes all comprise a universal reverse primer portion a different 3? target specific portion and different stems. The plurality of queried miRNAs can then be decoded in a plurality of amplification reactions.
