What is Biobanking? A Complete Guide
Biobanking is the systematic collection, processing, and long-term storage of biological samples for use in scientific research, clinical diagnostics, drug development, and personalised medicine. A biobank preserves biological material, including blood, tissue, DNA, cells, and organs, under controlled cryogenic conditions to maintain sample integrity for years or decades.
Modern biobanking underpins some of the most significant advances in medicine. Large population biobanks such as UK Biobank have enabled genome-wide association studies linking genetic variants to disease. Disease-specific biobanks support cancer research, rare disease diagnostics, and vaccine development. Reproductive biobanks form the backbone of IVF programmes, sperm donation, and fertility preservation services worldwide.
The global biobanking market has grown rapidly, driven by advances in genomics, personalised medicine, and the increasing need for well-characterised biological samples in pharmaceutical research. Quality cryogenic storage infrastructure is the foundation every biobank is built on.
Types of Biobank
Population Biobanks
Population biobanks collect samples and health data from large cohorts, often hundreds of thousands of participants, to enable epidemiological and genomic research. UK Biobank, with over 500,000 participants, is one of the largest examples globally and has contributed to thousands of peer-reviewed studies linking genetic variants to diseases including cancer, diabetes, and cardiovascular conditions.
Disease-Specific Biobanks
These focus on samples from patients with specific conditions, enabling targeted research into cancer, cardiovascular disease, neurological disorders, and rare genetic conditions. Tissue, blood, tumour biopsies, and cell line collections are common sample types. Many hospital trusts operate disease-specific biobanks alongside their clinical pathology departments.
Reproductive Biobanks
Reproductive biobanks store sperm, oocytes, embryos, and ovarian tissue for fertility treatment, donor programmes, and fertility preservation. In the UK they operate under strict HFEA regulation and require the highest standards of cryogenic equipment, quality management, and chain-of-custody documentation. Any failure of storage equipment in a reproductive biobank carries irreversible consequences.
Stem Cell and Cell Line Biobanks
These biobanks preserve stem cell populations and established cell lines for pharmaceutical research, drug screening, and regenerative medicine. The UK Stem Cell Bank, operated by the MHRA, is one of the foremost examples. Temperature stability and long-term equipment reliability are critical, as cell line drift or degradation can invalidate years of research.
Cord Blood Banks
Cord blood biobanks collect and store umbilical cord blood at birth, preserving haematopoietic stem cells for potential future therapeutic use in the donor or matched recipients. Both public and private cord blood banks operate in the UK, all requiring robust cryogenic storage infrastructure.
Cryogenic Equipment for Biobanking
The integrity of a biobank depends entirely on the quality and reliability of its cryogenic storage infrastructure. Cryolab has supplied cryogenic equipment to biobanks, research institutions, and reproductive medicine facilities for over 40 years, backed by ISO 9001:2015 certification and a specialist UK-based technical team.

How a Biobank Operates
Behind every biobank is a precise operational workflow designed to maintain sample integrity from the moment of collection to the point of retrieval, which may be decades later.
Sample Collection and Intake
Samples are collected under strict protocols governing consent, labelling, and handling conditions. Temperature-controlled transport is essential from the point of collection to the biobank facility, particularly for time-sensitive samples such as blood or tissue biopsies.
Processing and Preparation
Depending on sample type, processing may involve centrifugation, aliquoting, cell isolation, or addition of cryoprotective agents before freezing. Processing must be completed within defined time windows to avoid sample degradation.
Cryopreservation and Storage
Processed samples are cryopreserved using controlled-rate freezing or vitrification and transferred to long-term liquid nitrogen storage at -196 degrees Celsius. Each sample is assigned a unique identifier and catalogued within a laboratory information management system (LIMS).
Quality Management and Audit
Biobanks operate under continuous quality management frameworks. LN2 levels, temperature logs, and alarm systems are monitored around the clock. Regular audits verify sample inventory, storage conditions, and chain-of-custody records. ISO 20387 provides the international standard for biobanking quality management systems.
Sample Retrieval and Distribution
When samples are requested for research or clinical use, retrieval must be performed carefully to avoid compromising adjacent samples. Distribution to external sites requires validated dry-shipper transport to maintain cryogenic temperatures throughout transit.
Biobanking Regulations in the UK
Human Tissue Act 2004
The Human Tissue Act 2004 (HTA) governs the storage and use of human tissue in England, Wales, and Northern Ireland. Biobanks storing tissue samples must be licensed by the Human Tissue Authority and comply with its codes of practice covering consent, storage, and disposal.
HFEA Regulation
Reproductive biobanks storing embryos, oocytes, and sperm are regulated by the Human Fertilisation and Embryology Authority (HFEA). All such facilities must hold an HFEA licence and comply with the HFEA’s Code of Practice, including requirements for consent, storage duration, and facility standards.
UK GDPR and Data Protection
Biobanks hold sensitive personal and genetic data linked to biological samples. UK GDPR applies to the processing of this data, and biobanks must implement appropriate data governance frameworks, access controls, and participant rights procedures.
ISO 20387
ISO 20387 is the international standard for biobanking, covering requirements for competence, impartiality, and consistent operation of biobanks. Accreditation to ISO 20387 is increasingly expected by research funders and pharmaceutical partners as a mark of biobank quality.
Frequently Asked Questions About Biobanking
What is biobanking?
Biobanking is the collection, processing, and long-term cryogenic storage of biological samples such as blood, tissue, DNA, cells, and embryos for use in research, diagnostics, and clinical applications.
What samples are stored in a biobank?
Biobanks store a wide range of biological material including whole blood, plasma, serum, DNA, RNA, tissue biopsies, cell lines, stem cells, cord blood, sperm, oocytes, embryos, and ovarian tissue depending on the biobank’s purpose and regulatory framework.
What temperature are biobank samples stored at?
Most biobank samples are stored in liquid nitrogen at -196 degrees Celsius for long-term preservation. Some sample types may be held at -80 degrees Celsius in ultra-low temperature freezers for shorter-term storage, but cryogenic LN2 storage is the standard for indefinite preservation.
What cryogenic equipment does a biobank need?
A biobank requires liquid nitrogen storage tanks for long-term sample storage, controlled-rate freezers for the initial freeze of certain sample types, dry shippers for validated inter-site sample transfer, and liquid nitrogen dispensing vessels for safe LN2 handling during processing and maintenance workflows.
How long can biobank samples be stored?
Samples stored correctly at -196 degrees Celsius can remain viable indefinitely. Long-term biobanking studies have demonstrated sample integrity after several decades of cryogenic storage with no measurable degradation under stable conditions.
What regulations govern biobanking in the UK?
UK biobanks are regulated by the Human Tissue Authority (HTA) under the Human Tissue Act 2004, the HFEA for reproductive material, and UK GDPR for personal and genetic data. ISO 20387 provides the international quality management standard for biobanking operations.
How does cryopreservation support biobanking?
Cryopreservation is the primary preservation method used in biobanking. By storing samples at -196 degrees Celsius, all biological activity is halted, preventing degradation and maintaining sample integrity for future research or clinical use.
