METHOD OF AMPLIFYING MRNAS AND FOR PREPARING FULL LENGTH MRNA LIBRARIES

An inventive method for amplifying at least one RNA which is contained in a sample includes reverse transcribing the at least one RNA using a first primer, adding a dideoxy nucleotide which is modified in the 3′-position with a first partner of a pair of azide and alkyne molecules by action of a template independent polymerase to attach a single 3′-azide- or 3′-alkyne-modified dideoxy nucleotide at the 3′-end of the obtained cDNA, adding an adapter molecule which comprises a polynucleotide sequence and at its 5′-end a second partner of such pair of azide and alkyne molecules and ligating the adapter to the 3′-modified cDNA under formation of a triazole linkage, adding a second primer which is complementary to at least a part of the adapter molecule and which contains at its 3′-end a nucleotide which is complementary to the dideoxy nucleotide at the 3′-end of the cDNA to effect hybridization and binding of the second primer overlapping the triazole linkage, adding a third primer and amplifying the full length cDNA. Variations of this method are also disclosed. Uses of such method especially for preparing a full length RNA library and for sequencing of a plurality of RNAs contained in a sample, as well as reagent kits for performing such methods are also disclosed and included in the invention.
