PUMAdb : Princeton University MicroArray database

Your session is inactive. Please login.

The Princeton University MicroArray database (PUMAdb) stores raw and normalized data from microarray experiments, as well as their corresponding image files. In addition, PUMAdb provides interfaces for data retrieval, analysis and visualization. For mass spectrometry assays (proteomics and metabolomics), please visit the PUMPd project. For high-throughput sequencing assays, please visit the HTSEQ project.

Princeton researchers and their collaborators should register for a database account. Data is released to the public at the researcher's discretion or upon publication. If you are a world user, and are just trying to reach viewable data, either view our publications page or activate a world session.

PUMA Access: Access to non-public data is limited to registered Princeton researchers and their collaborators. Please see PUMAdb Registration for more specific information. If you have further questions regarding access, please e-mail the Princeton Microarray Database curators.


Scheduled downtime! The PUMA project has some upcoming scheduled downtime, so that we may update our system's hardware.

  1. NO ACCESS Saturday-Sunday April 26-27, while the database is being synchronized and configured
  2. READ-ONLY ACCESS Monday, April 28, for our final deployment check
Please accept our apologies for any inconvenience this might cause. Please let us know immediately if this conflicts with either class projects or other important research deadlines.
