Fresh human leukopaks

Cambridge Bioscience has a close collaboration with Research Donors, a London-based clinic, dedicated to the collection of human blood biospecimens for research purposes.

Our leukapheresis service provides researchers with fresh leukopaks containing 10 billion total nucleated cells on average from a single donor, with delivery available on the same or next day after collection (location dependent).

Collections are tailored to each researchers' specific needs, so the choice of volume, shipment temperature and blood group is yours. Leukopaks contain highly concentrated peripheral blood mononuclear cells (PBMC) which are ideal for applications including immunology and cell therapy (e.g. CAR-T) research, toxicology studies and high-throughput drug screening.

Research Donors is an HTA licensed, ISO 9001 2015 certified establishment with Research Ethics (REC) approval as a Research Tissue bank, as well as participating in the UK NEQAS QA scheme.

Leukapheresis process
With the wider use of cellular immune therapies, there is an increased demand from researchers for highly concentrated PBMC from a single individual. The traditional method of isolating PBMC from standard blood donations is limited by the maximum volume of blood that can be collected per donor (500 ml) and typically results in 1 to 2 million PMBC per ml of blood. Leukapheresis is the process by which a large number of total nucleated cells are separated from the blood of a single donor, resulting in a high concentration of PBMC, such as lymphocytes (T cells, B cells, and NK cells), monocytes and dendritic cells.

Leukapheresis process

1. Whole blood is collected from the donor via intravenous tube in one arm

2. Whole blood passes through a Spectra Optia® apheresis machine, which separates white blood cells from the blood

3. The white blood cells are collected in a leukopak for storage

4. The unused blood components are safely returned to the donor via intravenous tube in the other arm
