Summary
High-throughput SuperSAGE (HT-SuperSAGE) combines SuperSAGE with next-generation sequencing for deep transcriptome analysis. This method offers accurate gene annotation and multiplexing, reducing costs and time.
Area of Science:
- Molecular Biology
- Genomics
- Bioinformatics
Background:
- Serial Analysis of Gene Expression (SAGE) is a technique for transcript profiling.
- SuperSAGE utilizes longer sequence tags (26 bp) for improved gene annotation accuracy in eukaryotes.
- Existing SAGE methods can be time-consuming and costly.
Purpose of the Study:
- To present a detailed protocol for High-throughput SuperSAGE (HT-SuperSAGE).
- To enable deep transcriptome analysis using SuperSAGE combined with next-generation sequencing (NGS).
- To facilitate multiplexing and reduce the time, cost, and effort associated with transcriptome analysis.
Main Methods:
- Extraction of 26 bp tags from cDNA using the EcoP15I restriction enzyme.
- Integration of SuperSAGE with high-throughput sequencing technologies (Illumina Genome Analyzer and Applied Biosystems SOLiD).
- Detailed protocol development for HT-SuperSAGE.
Main Results:
- Successful combination of SuperSAGE with NGS technology.
- Development of HT-SuperSAGE for deep transcriptome analysis.
- Demonstration of multiplexing capabilities with reduced cost and time.
Conclusions:
- HT-SuperSAGE provides a powerful approach for deep transcriptome analysis.
- The method ensures secure tag-to-gene annotation across eukaryotic organisms.
- HT-SuperSAGE offers a more efficient and cost-effective alternative to traditional SAGE methods.

Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...
01:58Cell Specific Gene Expression
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
