The Oxford GI Biobank is primarily intended to provide validated biological samples in association with clinical data to support research into gastroenterological disease. The Biobank is strongly supported by the Translational Gastroenterology & Liver Unit (TGLU) that integrates the ORHT clinical department of Gastroenterology with the University of Oxford Nuffield Department of Medicine, Division of Experimental Medicine. Furthermore, by integrating the operation of the Biobank with the wider Oxford Radcliffe Biobank, samples will also be available to other researchers in the hospital, University, and more widely.

The major focus of research in the TGLU currently is inflammatory bowel disease, colorectal cancer, and innovative diagnostic and therapeutic approaches to these major diseases. Many samples in the Biobank will be derived from patients with IBD or with bowel cancer, and other samples, for instance from patients with irritable bowel syndrome, could form important control groups for comparison.

Typical uses of samples in the Biobank will include analysis of immunological and chemical changes associated with disease, characterisation of changes in cells and tissues with inflammation, and correlation of genetic background with disease activity.

Application Process for Project Proposals

Please download and complete the GI Cohort and IBD Cohort Request application form and save in the suggested name format NAME_SURNAME_DATE_TGLURequestForm. 

Click here  GI Cohort and IBD Cohort request form to download a copy.

The form must be completely filled in with as much detail as possible to be considered. Request forms are reviewed each month at the TGLU Internal Committee meeting which is usually held on the third Thursday of the month.

Once a proposal has been submitted, it will be reviewed by the TGLU Internal Committee and a decision/ comments will be sent back to the PI and/or the person who submitted the form.

To amend any existing sub-projects, please submit your form with your existing project proposal and clearly mark your amendments in RED lettering.

A formal approval letter will be sent to the PI of the project, as well as a conduct form. Projects may only start collecting samples under our ethics once they have received approval either by email or by formal approval letter.


The application submission deadline is up to (not including) ONE week before the third Thursday of every month​. Applications received after this will be automatically transferred to the next month's meeting.

The Lead Applicant or contact person will be required to attend this review meeting which is held via Teams on the third Thursday of the month.
