CREPE (CREate Primers and Evaluate): A Computational Tool for Large-Scale Primer Design and Specificity Analysis

Area of Science:

• Molecular Biology
• Bioinformatics

Background:

• Polymerase Chain Reaction (PCR) is a fundamental molecular biology technique.
• Manual primer design is time-consuming and prone to errors, especially for large-scale applications.
• Existing tools like Primer3 require additional pipelines for scaling and specificity analysis.

Purpose of the Study:

• To develop a scalable computational pipeline for automated primer design and specificity analysis.
• To overcome the limitations of manual primer design and enhance efficiency in PCR applications.
• To provide a tool optimized for targeted amplicon sequencing.

Main Methods:

• Integration of Primer3 and In-Silico PCR (ISPCR) functionalities into a single pipeline named CREPE.
• Development of a custom evaluation script for primer design and off-target analysis.
• Implementation of a workflow for targeted amplicon sequencing (TAS) on an Illumina platform.

Main Results:

• CREPE successfully performs large-scale primer design and specificity analysis.
• The pipeline provides primer pair information, off-target binding likelihood, and decision-making aids.
• Experimental validation demonstrated over 90% successful amplification for CREPE-approved primers.

Conclusions:

• CREPE is a novel software platform for parallelized primer design in PCR.
• The tool is optimized for targeted amplicon sequencing, improving efficiency and reliability.
• CREPE facilitates large-scale primer design, reducing manual effort and potential errors.
