Leukopaks: One Donor, Billions of White Blood Cells

Large volumes of white blood cells can be separated by apheresis (leukapheresis) while plasma and red blood cells are returned to the donor. Research Use Only (RUO) leukapheresis products collected from the same donor provide a reliable and consistent source of up to 10 billion immune cells, including peripheral blood mononuclear cells (PBMCs), rare CD34+ cells, for biomarker, immunology, autologous, and allogeneic cell therapy research and product development.

Leukopaks obtained from donors with confirmed disease closely resemble the autologous therapy that will be administered to patients, thereby providing more accurate data on immune cell subtypes and biomarkers.

Confirmed Disease State Leukopaks
Collected Under IRB Protocols

Trust Sanguine for Your Human Sample Research Needs:

Compliance & Quality Assured

Sanguine utilizes two internationally-recognized IRBs (Advarra and WCG IRB) for review and approval of all study protocols, specific study documentation, and study participant facing information. Both Advarra and WCG IRB are organized and operates in compliance with: FDA, OHRP, and International Conference on Harmonization (ICH).

Sanguine operates under an electronic informed consent process which executes 21 CFR part 11 compliant e-signatures, and Sanguine systems interacting with study participant information are HIPAA-compliant. Leukapheresis is conducted under an IRB-approved protocol at qualified blood clinic sites.
