Optimus Primer

Optimus Primer generates PCR primer pairs for targeted genomic regions from gene names and PCR parameters, accounting for gene isoforms and exon architecture to optimize amplicon design.

Key Features:

• Automated Primer Generation: Generates functional primer pairs from gene names and PCR parameters while accounting for gene isoforms and exon sizes and splitting large exons to maintain optimal amplicon lengths.
• Iterative Design with Primer3 Integration: Integrates Primer3 and performs up to four iterative design rounds with varying design parameters and stringencies.
• Enhanced Iteration Process: Automatically reruns regions that fail initial designs through three additional iterations with varied parameters, increasing successful primer pair recovery by 34% compared to a single-pass approach.
• Experimental Validation: Achieved a 93% experimental success rate when designing PCR primers for 77 genes associated with ulcerative colitis.

Scientific Applications:

• Exon-only re-sequencing: Design of PCR primer sets for targeted exon re-sequencing projects.
• Targeted genomic enrichment: Generation of primers for PCR-based targeted enrichment of genomic regions.
• Candidate gene studies: Application in candidate gene investigations, including studies of genes associated with ulcerative colitis.

Methodology:

The program accepts gene names and PCR parameters, then performs up to four iterative Primer3-based design iterations with varied stringencies and reruns failed regions through three additional iterations using varied parameters.
