Research Donors operates a service providing fresh, specific and highly characterised blood bio-specimens to life science researchers working throughout Europe. We have a dedicated blood donation facility and laboratory based in London where our paid volunteer donors donate blood for use in a wide range of basic and applied bio-, diagnostic- and medical- research applications. Our service offers researchers superior control over the blood bio-specimens that they use in their experiments and validation work. Our setup means that we are able to recruit specific donors, process samples in a wide range of collection devices, generate and test a broad range of blood derivative materials and deliver these to researchers across Europe overnight.
