    • 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.

    • The present invention relates to kits and methods for efficiently generating 5' capped RNA having a modified cap nucleotide and for use of such modified-nucleotide-capped RNA molecules. The invention is used to obtain novel compositions of such modified- nucleotide-capped RNA molecules. In particular, the present invention provides kits and methods for capping RNA using a modified cap nucleotide and a capping enzyme system, such as poxvirus capping enzyme. The present invention finds use for in vitro production o 5'-capped RNA having a modified cap nucleotide and for in vitro or in vivo production o polypeptides by in vitro or in vivo translation of such modified-nucleotide-capped RNA for a variety of research, therapeutic, and commercial applications. The invention also provides methods and kits for capturing or isolating uncapped RNA comprising primary RNA transcripts or RNA having a 5'-diphosphate, such as RNA synthesized in vitro or obtained from a biological source, including prokaryotic mRNA that is in a mixture with other prokaryotic and/or eukaryotic nucleic acids. The method for capturing modified-nucleotide- capped RNA also provides methods and kits for obtaining only type-specific or condition- specific modified-nucleotide-capped RNA by cap-dependent subtraction of that portion of the captured modified-nucleotide-capped RNA in cells of one type or condition that is the same as RNA in cells of another type or condition. The invention further provides methods and kits for using a capping enzyme system and modified cap nucleotides for labelin uncapped RNA comprising primary RNA transcripts or RNA having a 5 '-diphosphate with detectable dye or enzyme moieties.
