About us

Working with us

We are a specialist human biospecimen provider committed to accelerating biomedical discovery through ethically sourced, clinically verified human tissue, organ, blood and other biofluid/analtye samples.

Our work is grounded in a simple belief: the most meaningful scientific progress comes from research that reflects real human biology.

By supplying high‑integrity, well‑annotated biospecimens, we help researchers generate data that is more predictive, more translatable and ultimately more impactful.

Responsibly collected in accordance with the applicable regulations.

Our collections are sourced directly from trusted US hospitals, outpatient clinics body donation centers and transplant networks, ensuring clinical relevance, legal and ethical compliance and transparency.

Whether supporting early‑stage discovery, translational programs, medical device development or diagnostic validation, amongst other aims, we provide the dependable materials researchers need to move science forward with confidence.

What We Provide

We supply a broad range of human biospecimens, including:

Fresh, frozen and FFPE tumour/diseased tissue from most solid tumour types and a huge range of other diseases, as well as normal skin
Fresh whole blood, plasma, serum, buffy coat and PBMCs
Matched tumor and blood sets for integrated multi‑omic studies
Fresh bone marrow aspirate (subject to clinical availability)
Samples from donors with inflammatory, immune and chronic conditions, including endometriosis, COPD, IBD and diverticulitis, amongst others
Diagnostic remnants from an extensive range of conditions and controls including bloods, urine, stool, CSF and swabs, as appropriate, from cardiovascular, neurological, infectious and other conditions
Whole organs and anatomical parts, including both control and disease-relevant tissues

Custom protocols can be facilitated as part of prospective collections to meet specialised research needs.

Ethical, Responsible and Clinically Verified

Ethical sourcing is central to our mission. All specimens are collected under one or more of the following:

Informed patient/next of kin consent
IRB‑approved waiver of consent for diagnostic remnants
IRB‑approved protocols

Clinical information is obtained via medical records, and additional data—such as staging, treatment history or pathology confirmation—can be provided where available.

Our Mission

Supporting Human‑Relevant Science

Our mission is to empower researchers with biospecimens that reflect real human biology, enabling more accurate models, more reliable data and more meaningful scientific outcomes to help patients receive the treatments and diagnostics they need, and to help consumers to receive safe and effective products.

We believe that human‑based in vitro research is essential for improving the predictiveness of preclinical studies and eliminating reliance on unethical and irrelevant animal models. By providing high‑quality human samples, we help bridge the gap between laboratory research and clinical reality.

Our Values

Scientific Integrity

We prioritise accuracy, traceability and rigorous standards in every sample we provide.

Ethical Responsibility

We honour donor contributions through transparent, compliant and respectful sourcing practices.

Human‑Centred Research

We champion research approaches that better reflect human biology and improve translational relevance.

Accessibility for Researchers

We work to make high‑quality biospecimens available to teams of all sizes, from academic labs to global biopharma.

Giving Back Through Our Charity

Our corporate‑funded charity, a rabbit sanctuary called Tanglewood Warren, founded, hosted and managed by our CEO, reflects our commitment to compassion and community.
We provide lifelong medical care for previously unwanted pet rabbits with complex health needs, support fosterers and adopters, and contribute to improving animal welfare wherever possible.
This charitable work is an extension of our values: care, responsibility and a belief that suffering must be reduced and eliminated wherever possible.
