Key features & benefits

• High‑concentration PBMC yields: secure more than 10 billion total nucleated cells from a single apheresis donor, enabling complex immunology workflows, cell therapy development, and advanced functional testing.
• Extensively profiled donor population: work with donors screened for HLA type and viral status (CMV and EBV), with access to readily available recall donors ideal for longitudinal studies or repeat sampling.
• Adaptable, study‑specific collections: select full, half, quarter, or 1/10 leukopaks, with configurable options covering donor characteristics, scheduling, temperature management, and specialised handling protocols.
• Dependable, high‑viability samples: all leukopaks are rapidly processed after collection to preserve cellular integrity, supported by next‑day delivery throughout Europe and same‑day fulfilment for selected UK locations.
