The purpose of the research tissue bank is to provide fresh human biological samples for research. There is a current unmet need to provide anonymised fresh human biological samples to researchers undertaking clinical research across the Cambridge Biomedical Campus. This research protocol seeks to establish a panel of healthy volunteers who will consent to provide anonymised human biological samples on an ad hoc re-call basis for use by third party researchers associated with the Cambridge Biomedical Campus for clinical research purposes (University of Cambridge, NHS, Biopharma and Biotech employees and collaborators). No information will be fed back to volunteers, other than which organization the biological sample is being provided to.
