EMPIAR, the Electron Microscopy Public Image Archive, is a public resource for raw, 2D electron microscopy images. Here, you can browse, upload, and download and reprocess the thousands of raw, 2D images used to build a 3D structure. More ...

The EMPIAR-PDBj team at Osaka University assists Asian EM researchers with the transfer of big EM image data to EMPIAR. Instead of sending the data directly to the EBI (UK) via the internet, hard drives can also be sent to Osaka University by postal mail or via a courier service. As an alternative, internet transfer to our server in Osaka is also available. If you would like to take advantage of our submission services, please contact us first by e-mail before sending the data to us.

We have seen a large number of SARS-CoV-2 structures being determined rapidly and deposited into the PDB and EMDB, which provides a starting point for structure-guided drug discovery. In order to validate and reanalyze the data by the cryo-EM community, we would like to make the following urgent appeal. a) If you have deposited any cryo-EM structures related to SARS-CoV-2 to the EMDB (and possibly the PDB), please deposit the raw data to EMPIAR. b) If you have collected cryo-EM data related to SARS-CoV-2 but have not yet deposited a structure, please consider depositing the raw data to EMPIAR, so that the cryo-EM community could contribute to processing and model-building.
