Every investigator has complete ownership of his/her microarray experiment data. No other investigator can access or download data without having specific privileges. In order to facilitate data exchange among researchers, an investigator can assign limited or total access privileges to his/her data to other investigators registered in the system using the "Assign Privileges" option.

Investigators at Washington University who have conducted microarray experiments can download their data along with annotations using the "Download Chip Data" option. Once chips are hybridized, washed, analyzed and loaded onto the server, the investigator will receive an email notification from the facility stating that the data is ready and can be downloaded from this web page.

The gene annotation search utility allows the user to query genes/probesets of interest based on annotations from biomedical databases such as EntrezGene, UniGene, Gene Ontology, and dbSNP.

This search allows the user to view the expression profile of one or more genes of interest across all the samples for which the Biomedical Informatics Core has expression data.

This search allows the user to query for genes of interest and view statistically significant transcription factor binding sites that are conserved in evolution. A statistical model is established using pre-calculated binding sites to compute the probability score of a particular transcription factor binding to the promoter of a particular gene. For a set of correlated genes, this search identifies high scoring transcription factors by the hypothesis that they may be regulated by the same transcription factors. PAP also predicts other genes in the genome, which may be regulated by the same transcription factors.
