HemaFlex Cryopreserved Leukopaks
Gain the flexibility to work with high quality cryopreserved leukopaks that are ideal for basic research and early discovery. HemaFlex Cryopreserved Leukopaks are best utilized where controlled mononuclear cell numbers are beneficial and where continuity between RUO and GMP-compliant manufacturing processes is not required.
HemaFlex cryopreserved leukopaks are produced using continuous flow centrifugal technology (Spectra Optia® Apheresis System) directly into a collection bag containing ACD-A anticoagulant. HemaFlex Leukopaks are processed on-site shortly after collection and cryopreserved in CryoStor® CS10 freeze media using strict and consistent protocols, thus preserving quality and stability of the mononuclear cells.
Note: Cryopreserved leukopaks with SKUs CLP-19702, CLP-19705, CLP-19711, and CLP-19712 were produced based on total blood volume processed (BVP) with variable cell quantities per bag, while SKUs PB001CLP-RnD and PB001CLP-1-RnD-KIT contain a consistent number of white blood cells per bag.
A discount is applied that is proportional to the number of cryopreserved leukopak bags ordered. Up to eight cryopreserved leukopak bags can be included in a single shipment originating from one of our donor centers. Once received, either prepare cells for long-term storage in liquid nitrogen vapor phase or thaw for use. Storage in liquid phase nitrogen is NOT recommended. Short-term storage of cells (less than 2 weeks) at -80°C is acceptable but should be minimized to ensure maximum stability. Once thawed, samples must be used immediately.
