comment: Total RNA is isolated from cells and mRNA is purified by targeting the 3' polyadenylated (poly(A)) tail with poly(T) oligos covalently attached to a substrate. Next, cDNA fragments are generated either by hydrolysis of RNA into 200-300 base oligonucleotides, preceded by reverse transcription, or by reverse transcription initiated by random primers. The cDNA second strand is synthesized, fragments are adapter ligated and high-throughput sequencing is performed by Roche 454, Illumina, ABI-SOLiD, or another HT sequencing technology. Resulting sort reads are aligned against a reference genome, and downstream analysis is performed.
