RACE - Rapid Amplification of cDNA Ends

RACE - Rapid Amplification of cDNA Ends

Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific primer.

Chromatin Packaging

Chromatin Packaging

Each human somatic cell contains 6 billion base pairs of DNA. Each base pair is 0.34 nm long, meaning each diploid cell contains a staggering 2 meters of DNA. This long DNA strand is packed inside a nucleus measuring only 10-20 microns in diameter with the help of specialized DNA-binding proteins called histones. Together they form a compact DNA-protein complex called chromatin. The chromatin is further compacted into higher-order structures. The highest level of compaction is achieved during...

Summary

Analyzing rare messages in cDNA libraries is challenging. Duplex-specific nuclease (DSN) normalization creates equalized cDNA, enabling efficient rare transcript discovery and analysis.

Area of Science:

Molecular Biology
Genomics
Biotechnology

Background:

Analyzing rare messages in cDNA libraries is difficult due to transcript abundance variations.
Equalized (normalized) cDNA is essential for rare transcript searches and analyses.
Various cDNA normalization methods exist, with some optimized for full-length enriched cDNA.

Purpose of the Study:

To present a cDNA normalization method using duplex-specific nuclease (DSN).
To enable efficient rare transcript discovery and analysis.
To highlight applications in transcriptome analysis and functional screening.

Main Methods:

Utilizes duplex-specific nuclease (DSN) from kamchatka crab.
Applies DSN properties for cDNA normalization.
