CAGE™ Preparation Kit

CAGE Preparation Kit is a ready-to-use product that includes reagents* and the protocol necessary for the preparation of a CAGE library, which allows the easy introduction of Cap Analysis of Gene Expression, CAGE, into your R&D.
* Note: Reverse Transcriptase is not inclued.

CAGE enables sequencing and mapping of short tags derived from the 5'-end of mRNA, thereby quantifying the frequency of tag sequences. 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.

A sequencing run using one channel on the Illumina Sequencer can yield over 4,000,000 reads per sample. Expression profiles obtained from DeepCAGE (i.e., combination of next-generation sequencing with next-generation expressing profiling) will be powerful tools for various gene expression analyses and genome annotation projects.

What can CAGE offer you?

Applications

  • Genome-wide gene-expression analysis
  • Prediction of promoter sites
  • Quantitative mRNA expression profiling

Examples of actual usage of CAGE

  • "Functional Annotation of Mouse (FANTOM) project" by RIKEN
  • "Encyclopedia of DNA Elements (ENCODE) project" by the National Institute of Health (NIH)
  • "Gene Networks project" by the Ministry of Education, Culture, Sports, Science and Technology

Product specifications

  • The cap-trapper method involves capturing the 5'-cap of mRNA while removing rRNA.
  • The random priming method allows generation of hybridization products from non-coding mRNAs, in addition to those from mRNAs
  • The use of barcodes allows multiplex sequence analysis.
  • Prepared CAGE libraries can be analyzed with an Illumina next-generation DNA sequencer.
  • Note: the CAGE Kit does not contain reverse transcriptase.

For data analysis, Platform system for next-generation sequencing (NGS) data analysis is available at the National Institutes of Genetics.

Technical Information

CAGE is a novel approach for identifying promoters and gene expression profiling.
CAGE is based on full-length cDNA library technology for next-generation sequencing technologies, where an adaptor is ligated to the 5’ end of each full-length cDNA. By mapping genomic sequences on the CAGE tags, transcriptional start sites can be identified. Thus, CAGE can be a powerful tool for discovery of novel genes, genome-wide gene-expression profiling, and promoter analysis.

Difference from RNA-Seq and other gene analysis techniques

Different from Microarray and RNA-seq, CAGE is able to accurately identify transcriptional start sites (TSSs) and the corresponding promoter regions through sequencing the 3’ end of cDNA (5’ end of RNA). This makes CAGE a powerful tool to analyze the gene regulation in the TSSs level, enabling analysis of the gene regulated by multiple alternative promoters. Therefore, CAGE can serve as a new perspective approach for genome annotation, by elucidating transcriptional signaling cascades, and performing other functions.
