About Us

Cyto-care.eu GmbH is providing cell products for biomedical research, drug discovery, process development and cell and gene therapy starting material. Founded 2011, we are very experienced in performing leukapheresis in patients and healthy donors.

Leukopaks are enriched leukapheresis products collected from peripheral blood. It is composed of mononuclear cells (MNC, T-/B-lymphocytes, monocytes, NK cells) with minimal contamination of granulocytes, red blood cells, platelets and plasma. Leukopaks contain a higher concentration of cells as compared to standard venipuncture collection methods or buffy coat products.

Our leukopaks are collected in our cooperative cell collection center in Vienna. All work is performed under EU compliant collection procedures according to controlled GMP/GCP conditions. These ensure a high consistency, high cell yields and a high reproducibility of our cell products.

Our work relies on:

  • A strict QM system with SOPs, regular trainings
  • Strictly controlled collections
  • IDM testing at the day of collection to ensure a maximum of safety
  • Reliable delivery logistics
  • Service orientation

We believe in the potential of cell therapy. Since 2011 we have been:

  • A reliable provider to biotechnology, CMOs and large pharma companies
  • Participating in clinical trials
  • Presenting at international conferences and meetings
