StemExpress, founded in 2010 and headquartered in Folsom, California, is a leading supplier of human biospecimens and isolated primary cells for biomedical research. Its product portfolio includes a variety of biological materials such as bone marrow, peripheral blood, cord blood, and mobilized peripheral blood.StemExpress offers the CellsExpress™ bulk cell isolation service, which provides premium products in multiple aliquot sizes to meet experimental reproducibility requirements. This service can process up to 100 billion total nucleated cells (TNCs)—equivalent to the guaranteed cell count of its standard leukopak product—and isolate specific target cell types. All cells are isolated from fresh source material and cryopreserved immediately after isolation using high-quality reagents, ensuring optimal cell quality and viability.

1. Leukopaks

The company provides peripheral blood leukopaks enriched with peripheral blood mononuclear cells (PBMCs) that contain low levels of granulocytes and red blood cells. This highly enriched PBMC component requires minimal downstream processing and can be directly used to isolate high-yield immune cells such as CD4+ T cells, CD8+ T cells, CD19+ B cells, monocytes, and other immune cell types.

High cell yields improve the reproducibility of single-donor experiments, reduce variability among identical cell types, and enhance experimental scalability. In addition, up to 12 leukopaks can be collected from the same donor within one year, providing sufficient PBMC quantities for large-scale studies.

CGT Global also offers disease-state leukopaks for research. Leukopaks are shipped the same day or cryopreserved immediately, ensuring high product viability and quality. Key advantages include high PBMC concentration, ≥95% viability (fresh), HBV/HCV/HIV negative status, and IRB certification.

2. Bone Marrow

The company supplies whole human bone marrow and bone marrow-derived primary cells, collected by certified medical professionals from up to four sites of the posterior iliac crest, with a total volume of up to 200 mL. Human bone marrow samples can be shipped immediately to customers or processed onsite in an FDA-registered laboratory into specific primary cell populations.

3. Whole Blood Products

CGT Global provides high-quality human whole blood products for both research and clinical applications, including RUO, GMP, and disease-state donor options. Whole blood is collected in FDA-registered and CLIA-certified facilities and can be supplied fresh or cryopreserved, with customizable collection protocols and comprehensive donor metadata.

These whole blood products are ideal for PBMC isolation, immunological assays, assay development, and cell therapy workflows, supporting applications ranging from preclinical research to GMP manufacturing. The company also offers donor recall, pre-screening, and flexible scheduling services through its facilities in Boston, Philadelphia, and Folsom.

4. Cord Blood

As a leading supplier of human cord blood and primary cells, CGT Global collects cord blood by drawing from the umbilical vein needle into sterile collection bags containing the anticoagulant citrate phosphate dextrose (CPD). Cord blood can be shipped directly to customers after collection or processed into specific primary cell populations in GLP-compliant laboratories.

5. Isolated Cells

CGT Global offers a comprehensive selection of isolated cell products designed to support a wide range of biomedical and life science research applications. These high-quality cells are carefully sourced, isolated, and processed to ensure optimal viability and functionality, making them ideal for applications such as drug discovery, disease modeling, and cell-based assays.

The product catalog includes primary cells, stem cells, immune cells, and other specialized cell types. Each cell product is accompanied by detailed data and quality control documentation, ensuring experimental reproducibility and accuracy. These reliable resources provide researchers in fields such as cancer research, regenerative medicine, and immunotherapy with the consistency and precision needed to drive breakthrough discoveries.
