SuperSAGE: Powerful serial analysis of gene expression

Abstract

SuperSAGE is a variant of the Serial Analysis of Gene Expression (SAGE) technology, based on counting transcripts by sequencing analysis of short sequence tags. In SuperSAGE, 26 bp tags are extracted from cDNA using the Type III restriction endonuclease EcoP15I. The use of a longer tag size in SuperSAGE allows a secure tag-to-gene annotation in any eukaryotic organism. We have succeeded in combining SuperSAGE and high-throughput sequencing technology (Now- or Next-Generation Sequencing, NGS) in an approach we call High-throughput SuperSAGE (HT-SuperSAGE). This approach allows deep transcriptome analysis and multiplexing, while reducing time, cost, and effort for the analysis. In this chapter, we present the detailed HT-SuperSAGE protocol for both the Illumina Genome Analyzer and also the AppliedBiosystems SOLiD sequencer. © 2012 Springer Science+Business Media, LLC.
