    摘要: The present invention provides methods for the sequencing of all RNA species within an RNA sample, such as the RNA content obtained from a cell, a tissue, a living organism, or from an artificial source. RNA molecules within the samples are labeled in a RNA-specific manner prior to immobilization on a solid support. One label is used to mark the location of the RNA molecule on the solid support, whereas the second label is used to mark selectively the S′ end of full-length mRNA molecules. RNA molecules are sequenced while being bound to the solid support in one or more sequencing reactions, and sequences of individual RNA molecules can be forwarded to computational analysis for assembling sequence information from individual sequencing reads obtained from the same location on the solid support. Not only unsupervised expression profiling on a genome-wide scale, but also the direct analysis of RNA-RNA interactions become possible as revealed by the analysis of the sequencing information obtained along with genomic information.

    摘要: Disclosed is a method for making full-length CDNA libraries, which is for making libraries of cDNAs having a length corresponding to a full-length of mRNAs and comprises the following steps of; binding a tag molecule to a diol structure present in 5′ Cap (7MeGpppN) sites of mRNAs, forming RNA-DNA hybrids by reverse transcription using primers such as oligo dT and the mRNAs connected with the tag molecule as templates, and separating RNA-DNA hybrids carrying a DNA corresponding to a full-length of mRNAs from the RNA-DNA hybrids formed above by using function of the tag molecule. To obtain mRNA connected with a tag molecule, the diol structure present in 5′ Cap site of mRNA is subjected to a ring-open reaction by oxidation with sodium periodate to form a dialdehyde and the dialdehyde is reacted with a tag molecule having a hydrazine terminus. According to the present invention, there are provided a novel method capable of efficiently labeling 5′ Cap site and a method for making full-length cDNA libraries utilizing the labeling method.
