Microarray oligonucleotide probe designer (MOPeD): A web service

Area of Science:

• Genomics
• Bioinformatics
• Molecular Biology

Background:

• Genomic selection methods utilize high-density oligonucleotide microarrays and next-generation DNA sequencing.
• Characterizing genomic variation in complex eukaryotic genomes presents challenges in selecting appropriate oligonucleotide probes.

Purpose of the Study:

• To develop an automated software solution for designing custom genomic selection microarrays.
• To provide researchers with a tool for optimizing microarray design for specific genomic regions.

Main Methods:

• Developed MOPeD (Microarray Oligonucleotide Probe Designer), a web-based software package.
• Incorporated design parameters such as probe sequence uniqueness, melting temperature, hairpin formation, and single nucleotide polymorphisms.
• Generated probe databases for human, mouse, and rhesus macaque genomes.

Main Results:

• MOPeD-designed microarrays showed superior performance in human X chromosome exome sequencing compared to proprietary algorithms.
• Experimental validation in mouse identified known mutations in targeted genomic regions.
• Successfully designed and validated microarrays for human and mouse genomic studies.

Conclusions:

• The open-source MOPeD software is a valuable resource for sequence-based studies of complex eukaryotic genomes.
• Automated probe design enhances the efficiency and accuracy of genomic selection microarray development.
• MOPeD facilitates custom microarray design for diverse research applications in genomics.
