Application Process

Applications can be made online via the sample search facility, which can be accessed once you set up a free and instant account. Once an application with a signed Material Transfer Agreement has been received by WCB it will be circulated to the external review panel. This panel is made up of international experts who review projects to ensure a good use of samples in sound scientific projects. The application process usually takes 3-4 weeks unless the reviewers request additional information. This can increase the review time, so try to ensure that your application contains all supporting information and numbers of samples are clearly defined with relevant justification.

The progress of an application can be tracked online.

Following approval, the WCB office will inform you of the likely time to supply of the required samples. This will depend upon the number and type of samples requested. If nucleic acids are to be extracted to fulfil a request, the resulting quantity and quality of the DNA or RNA cannot be guaranteed prior to extraction. Unsuitable extractions may therefore reduce the number of suitable, available samples. Shipping arrangements and costs are to be arranged and met by the receiving researcher/group. A contribution towards cost recovery fee will be invoiced to the receiving group.

After supply

Samples can only be used for the purposes stated in an approved application. If further or extended work is proposed, a document detailing the proposed new or change of use should be submitted to WCB ( This will be submitted to the review panel for consideration. Part of the conditions of supply stipulate that WCB should be acknowledged as sample suppliers in any article, paper, poster, etc. generated from research carried out on samples supplied by stating, "Biosamples were obtained from the Wales Cancer Bank (DOI:"

WCB should be informed of the publication. WCB will be asking for the return of raw data from all supplied projects, post publication or IP exploitation to collate in a data warehouse for future bioinformatics.
