CAGE-TSSchip: promoter-based expression profiling using the 5'-leading label of capped transcripts

Cap analysis gene expression (CAGE) technology has revealed numerous transcription start sites (TSSs) in mammals and has suggested complex promoter-based patterns of regulation. We developed the CAGE-TSSchip to detect promoter-based transcriptional activity. The CAGE-TSSchip is a customized oligonuc...

Sumario:Cap analysis gene expression (CAGE) technology has revealed numerous transcription start sites (TSSs) in mammals and has suggested complex promoter-based patterns of regulation. We developed the CAGE-TSSchip to detect promoter-based transcriptional activity. The CAGE-TSSchip is a customized oligonucleotide array that targets known TSSs identified by CAGE. A new labeling method, labeling capped transcripts from the 5'-end, had to be developed. The CAGE-TSSchip is accurate and sensitive, and represents the activity of each TSS.
