Cryopreserved Leukopaks

Cryopreserved leukopaks give you the flexibility to schedule your processes on your timeline and have ready-to-thaw inventory on hand that will meet your processing schedule needs. Read our whitepaper which demonstrates how cryopreservation can preserve white blood cell yields and viability, and maintain therapeutic cell ratios comparable to freshly collected leukopaks.

We are excited to announce a new level of cooperation with HemaCare facilitated by our recent acquisition by Charles River. Key benefits of our product harmonization include:

  • Access to a consistent and continuous supply of starting material sourced from coast-to-coast collection centers
  • Selection of donor(s) meeting your criteria via our robust highly-characterized recallable donor pool
  • Consistent product with the highest achievable purity and yield from same day collection and processing

Learn more about our product harmonization and what it means to you.

Product codes 19702, 19705, 19711, 19712, and 19713 have been discontinued. Please refer below for the replacement product.

Non-mobilized leukopaks are collected under an IRB-approved protocol from normal healthy individuals and qualified in accordance with current regulations and requirements for donors of transfusable blood components. This includes screening with the Uniform Donor History Questionnaire that was developed by the AABB and accepted by the Food and Drug Administration for screening of donors of transfusable blood components.

All donors are prescreened for evidence of transfusion-transmissible infectious diseases with the standard panel of tests used to screen blood products for transfusion acceptability, which include HBV, HCV, HIV, HTLV, WNV, Trypanosoma cruzi, and Syphilis. Testing for exposure to Babesia microti is performed for donors in selected geographic regions in accordance with FDA recommendations.

Leukopaks are collected in our FDA-registered collection centers by leukapheresis using the Spectra Optia® Apheresis System and then quickly cryopreserved on site in CryoStor® CS10 freeze media using a controlled rate cryopreservation procedure.

Cryopreserved leukopaks are packaged and shipped on the date of cryopreservation for overnight delivery. In some locations, same day delivery is possible.

Products are packaged in a Cryoport® shipper and shipped on liquid nitrogen. Shipping on dry ice is available upon request, but not recommended. </p/>

Continuous temperature monitoring data tracking devices are available for use at the customer’s request or as defined by the protocol.
