Human Peripheral Blood - Your source for quality fresh and cryopreserved human cells

Disease State Products

StemExpress is a premier provider of human diseased blood, plasma, serum, and peripheral blood mononuclear cells (PBMCs). Using our strategically located collection centers and our partnering hospitals, we are able to ensure access to donors and the delivery of fresh products to researchers in need of rare blood samples. Our disease state samples are from donors with various autoimmune diseases, infectious diseases, cancers, and other diseases. We provide patient samples that are ideal for research, as well as new product development and validation.

Samples are collected from volunteers participating in Institutional Review Board (IRB) approved donor programs. All collections follow a standardized collection procedure to guarantee consistency from donor to donor, eliminating variability in the collection procedure. In addition, donors may be eligible for recall every 8 weeks (pending the health of the donor), which allows for the study of disease progression within a single donor.
