Peripheral Blood Leukopak

Our Fresh Leukopaks are collected from healthy IRB consented donors, that have been tested negative for HBV, HCV, and HIV. Leukopaks are collected using the Spectra Optia® Apheresis System, where cell-rich mononuclear cells are extracted using a continuous flow system directly into a sterile collection bag containing the anticoagulant ACD-A. CGT Clinics are CLIA Certified and FDA Registered. Up to 12 Fresh Leukopak collections can be performed on the same donor in a given year, providing an ample amount of PBMCs for large-scale experiments and research studies. Additionally, 200-300mL of plasma can be collected at the time of the donor draw.
