MultiPriDe: automated batch development of quantitative real-time PCR primers

Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) is a commonly employed gene expression quantification technique. This requires the development of appropriately targeted oligonucleotide primers, which necessitates the identification of ideal amplicons, development of optimized oligonucleotide sequences under most favorable pre-determined reaction conditions, and management of the resultant target-oligonucleotide pair information for each gene to be studied. The Primer3 utility exists for development of oligonucleotide primers and fills that role effectively. However, the manual process of identifying target sites and individually generating primers is inefficient and prone to user-introduced error, especially when a large number of genes are to be examined. We have developed MultiPriDe (Multiple Primer Design), a Perl utility that accepts batch lists of Gene database identifiers, collects available intron and exon position data critical to qRT-PCR primer development, and supplies these sites as identified targets for the Primer3 utility. This automated 'gene to primer' procedure is coupled with a set of optimized hybridization conditions used by the Primer3 utility to maximize successful primer design. MultiPriDe and assembled repeat libraries are available upon request. Please direct requests to [email protected].
