NCBI released the Probe database in 2005 as a registry of nucleic acid reagents for biomedical research. At that time array-based assays were prevalent, but have since declined with the advent of short read sequencing. As a result, NCBI will retire the web interface for the Probe database in April 2020. You can continue accessing the content of the database on the NCBI FTP site, but it will no longer be updated. As of this announcement, Probe will no longer be accepting new submissions.
If you have questions or concerns about this retirement, we’d love to hear from you. Please comment here or contact us at firstname.lastname@example.org.
