HemBio started collecting samples in November 2012 with the aim of extensive sample series (plasma, serum, viable frozen bone marrow cells, skin biopsies) taken at different timepoints of disease (e.g. at diagnosis, at remission, and at possible relapse). HemBio has recruited over 3500 hematological patients and collected over 30 000 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 HemBio website.
