Welcome to probeBase

Due to some system maintenance, the submission of new probes or primers is disabled right now!

probeBase is a curated database of rRNA-targeted oligonucleotide probes and primers.

Search probeBase for target organisms, probe names, primers, target sites, references, etc.  

Match rRNA sequence(s) against probeBase and find all published probes targeting your sequence(s).  

Match partial rRNA sequence(s) against full-length sequences in SILVA and find published probes potentially targeting your sequence(s).

View lists of probes (according to probe categories), primers, microarrays, references, etc.

This is a completely new implementation of probeBase including a new database architecture and environment to accommodate computationally efficient access and improved search and sequence match functions.
The previous version of probeBase is still available at www.microbial-ecology.net/probebase_old.
