Abstract 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. Background Many genome sequencing projects of model species are finished and a large number of full-length cDNAs have been isolated. Trends in large-scale life .
