Tissue Solutions are able to provide fresh and cryopreserved peripheral blood leukopaks and mobilised peripheral blood leukopaks. A leukopak contains a higher concentration of cells as compared to standard venipuncture collection methods or buffy coat products.
Leukopaks from mobilized peripheral blood are collected from normal, healthy donors on a specific dosing regimen. These injections are designed to stimulate the bone marrow in order to produce a large number of hematopoietic and progenitor stem cells, which increases their frequency in the peripheral bloodstream.
