Abstract: Assays can be used to detect mutations found in neoplasms of the pancreas, as well as for other neoplasms and other uses. Nucleic acids can be captured from body fluids such as cyst fluids. Thousands of oligonucleotides can be synthesized in parallel, amplified and ligated together. The ligated products can be further amplified. The amplified, ligated products are used to capture complementary DNA sequences, which can be analyzed, for example by massively parallel sequencing.

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.

Abstract: The method of identifying Date Palm gender using SCAR primers includes using modern genetics techniques for detecting a novel sex-linked marker (SEQ ID NO: 1) in a Date Palm sample. The presence of the Date Palm sex-linked marker (SEQ ID NO: 1) in the sample is indicative that the sample is from a male Date Palm plant. The method of identifying Date Palm gender to determine the gender of Date Palms can be used to determine the gender of Date Palms of any age.
