DNAFOM CAGE library preparation services ensure all your bases are covered providing an end-to-end unique transcriptome solution including library construction, sequencing on the Illumina NextSeq platforms and comprehensive data analysis.

CAGE, Cap Analysis of Gene Expression, enables sequencing and mapping of CAGE sequencing reads derived from the 5'-end of mRNA and RNA polymeraseⅡproducts, thereby quantifying the frequency of each RNA. A distinctive feature of CAGE is its capability to accurately identify promoter sites for each transcript and obtain gene expression profiles based on identified promoters.

As genome sequence variations are beginning to be understood on an individual level, attention is now turning to the transcriptome and the effects that differential levels of gene transcription and its promoter activities have on phenotype such as disease susceptibility, cancer progression and biomarker discovery. Expression profiles obtained from CAGE in combination of next-generation sequencing will be powerful tools for various transcriptome projects.

□Applications
