Rapid and simple method of qPCR primer design

Methods Mol Biol. 2015:1275:173-9. doi: 10.1007/978-1-4939-2365-6_13.

Abstract

Quantitative real-time polymerase chain reaction (qPCR) is a powerful tool for analysis and quantification of gene expression. It is advantageous compared to traditional gel-based method of PCR, as gene expression can be visualized "real-time" using a computer. In qPCR, a reporter dye system is used which intercalates with DNA's region of interest and detects DNA amplification. Some of the popular reporter systems used in qPCR are the following: Molecular Beacon(®), SYBR Green(®), and Taqman(®). However, success of qPCR depends on the optimal primers used. Some of the considerations for primer design are the following: GC content, primer self-dimer, or secondary structure formation. Freely available software could be used for ideal qPCR primer design. Here we have shown how to use some freely available web-based software programs (such as Primerquest(®), Unafold(®), and Beacon designer(®)) to design qPCR primers.
