The available collections from all biobanks of BBMRI.be can be found in the BBMRI-BE Directory
The BBMRI.be Directory is a collection level catalog which gives you a glance of the material that is available at our biobanks and is freely available for all researchers.

In the Directory, you can filter the biobanks with your criteria. After the search,  you can contact all biobanks of interest at once through the communication platform of BBMRI-ERIC (the Negotiator). The Negotiator substantially simplifies the communication steps that are necessary to obtain information on the availability of relevant samples/data, particularly if the researchers need to communicate with multiple candidate biobanks.

If you do not find the samples you are looking for in the BBMRI.be Directory, then go have look at the BBMRI-ERIC Directory, the biggest biobanking catalogue on the globe,w hich harbours all collections of BBMRI-ERIC.
