20090053775 | COPY DNA AND SENSE RNA - The present invention relates generally to methods, compositions and kits for synthesizing sense RNA molecules from one or more RNA molecules of interest in a sample. In exemplary embodiments, the methods use a terminal tagging oligoribonucleotide (rTTO) to join a DNA sequence tag to the 3′-termini of first-strand cDNA molecules. The use of an rTTO comprising ribonucleotides results in decreased oligonucleotide-derived background synthesis of RNA in the absence of sample RNA and, surprisingly and unexpectedly, also results in significantly increased yields of sense RNA molecules that exhibit sequences that are substantially identical to those of the RNA molecules of interest in the sample. The sense RNA molecules also have an RNA sequence tag on their 5′-termini that is useful for fixing the lengths of sense RNA molecules that are synthesized in a second or subsequent round. | 02-26-2009 |

20110076728 | TARGET AMPLIFICATION AND SEQUENCING WITH PRIMERS COMPRISING TRIPLEX FORMING MONOMER UNITS - The current inventors have discovered that the incorporation of a triplex forming monomer unit into oligonucleotides surprisingly gives the oligonucleotide a number of favorable characteristics. The oligonucleotides are advantageous because they allow modulation of the melting temperature of an oligonucleotide, they have improved sequence specificity and they can form triplexes by Hoogsteen or reverse Hoogsteen base pairing with double stranded nucleic acids. Moreover, some of the oligonucleotides of the invention have useful fluorescent characteristics, and the oligonucleotides comprising a triplex forming monomer can be used as substrates for enzymatic manipulations such as primer extension. | 03-31-2011 |
20110129878 | BIOREACTIVE AGENTS - This invention relates to agents and conjugates that can be used to detect and isolate target components from complex mixtures such as nucleic acids from biological samples, cells from bodily fluids, and nascent proteins from translation reactions. Agents comprise a detectable moiety bound to a photoreactive moiety. Conjugates comprise agents coupled to substrates by covalent bounds which can be selectively cleaved with the administration of electromagnetic radiation. Targets substances labeled with detectable molecules can be easily identified and separated from a heterologous mixture of substances. Exposure of the conjugate to radiation releases the target in a functional form and completely unaltered. Using photocleavable molecular precursors as the conjugates, label can be incorporated into macromolecules, the nascent macromolecules isolated and the label completely removed. The invention also relates to targets isolated with these conjugates which may be useful as pharmaceutical agents or compositions that can be administered to humans and other mammals. Useful compositions include biological agents such as nucleic acids, proteins, lipids and cytokines. Conjugates can also be used to monitor the pathway and half-life of pharmaceutical composition in vivo and for diagnostic, therapeutic and prophylactic purposes. The invention also relates to kits comprised of agents and conjugates that can be used for the detection of diseases, disorders and nearly any individual substance in a complex background of substances. | 06-02-2011 |
