The Centre de Ressources Biologiques-Tumorotheque ICO is a biobank integrated in a clinical cancer center (ICO, Institut de Cancerologie de l’Ouest, Saint-Herblain, FR) that collects tissues (snap frozen, FFPE, TMA) and biological (serum, plasma, DNA, RNA, stools, etc) samples from oncology patients and dedicated to translational research. The biobank started its activities in 2002 and is certified NF S 96 900. Activities are framed by a quality management system with established and validated SOPs for all work procedures. Samples stored into the biobank are available for both academic as well as commercial researchers, through a defined access procedure. Currently the bioresources consist in more than 99.500 samples with informed consent and associated clinical data.
