There are many breakthroughs today in designing DNA chip-based experiments, and the most important part is using the most relevant and corresponding array. In the case of pigs, compared to human or mouse experiments, the genomes are not entirely annotated; this means that chips that represent all the genes are not commercially available.

Regarding pigs case, there is ongoing work on genome sequence even though there are also custom-made microarrays; but ultimately they lack probe annotations as there is no source for cDNA in the pig.

Through our website we provide Swine Protein-Annotated Oligonucleotide Microarray or Pigoligoarray related information, to further enhance porcine tissues research.
