    摘要: 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 of 5′-capped RNA having a modified cap nucleotide and for in vitro or in vivo production of 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 labeling uncapped RNA comprising primary RNA transcripts or RNA having a 5′-diphosphate with detectable dye or enzyme moieties.

    摘要: The present invention provides methods, compositions and kits for using a transposase and a transposon end for generating extensive fragmentation and 5′-tagging of double-stranded target DNA in vitro, then using a DNA polymerase for generating 5′- and 3′-tagged single-stranded DNA fragments without performing a PCR amplification reaction, wherein the first tag on the 5′-ends exhibits the sequence of the transferred transposon end and optionally, an additional arbitrary sequence, and the second tag on the 3′-ends exhibits a different sequence from the sequence exhibited by the first tag. The method is useful for generating 5′- and 3′-tagged DNA fragments for use in a variety of processes, including processes for metagenomic analysis of DNA in environmental samples, copy number variation (CNV) analysis of DNA, and comparative genomic sequencing (CGS), including massively parallel DNA sequencing (so-called “next-generation sequencing.)
