Hematological Biobank (FHRB) offers access to high-quality clinical patient material linked to comprehensive registry data and molecular characterization. FHRB started collecting samples in November 2012 with the aim of extensive sample series (plasma, serum, whole blood, bone marrow cells, skin biopsies) taken at different timepoints of disease (e.g. at diagnosis, at remission, and at possible relapse). FHRB has recruited over 2100 hematological patients and collected over 16 000 samples. Sample and data are available for medical research as well as for R&D activities. Instructions for sample and data application can be found on FHRB website.
