Overview

Cryopreserved leukopaks provide a ready-to-use inventory of mononuclear leukocytes, principally lymphocytes and monocytes, for studies where immediate processing of fresh material is impractical. Material is collected by leukapheresis from pre-screened healthy donors and frozen using a controlled-rate process with cryoprotectant.

Each cryopreserved unit comes from a single fresh leukopak. A full cryopreserved leukopak yields 3 to 6 quarter cryobags of about 2.5 × 109 TNC each from one donor collection, with a minimum of 3 bags (about 7.5 × 109 TNC). Final bag number depends on donor yield.

Why choose our cryopreserved leukopaks?

  • Defined post-thaw performance: viability at least 90% and recovery at least 80%
  • Flexible scheduling: long-term storage reduces dependence on immediate processing
  • Screened donors: medically examined donors with prior plasma donation experience, and every donation tested against a full viral-marker panel
  • Donor documentation: age, gender, race, blood type and viral-screening records

Applications

  • Cell therapy research and process development, including CAR-T, stem cell and immunotherapy workflows
  • Assay development, validation and proficiency testing
  • Study scheduling and inventory planning

FAQs

When should I choose cryopreserved rather than fresh?

Cryopreserved material offers greater scheduling flexibility and defined post-thaw performance specifications, so it suits studies where fresh material cannot be processed straight away.

How many bags are in a full cryopreserved leukopak?

A full leukopak yields 3 to 6 quarter cryobags from one donor, with a minimum of 3. The final number depends on donor yield.

Can I specify donor requirements?

Yes. HLA-matched, recallable and specified donors (for example by age, BMI or ethnicity) can be sourced on request. These may carry an extra charge and depend on donor availability.

What virology testing is carried out?

Every donation is tested for HIV, HBV and HCV by NAT and serology, plus HTLV I/II, HAV, HEV, parvovirus B19, West Nile virus, syphilis and Chagas.
