Custom Solutions for Human Primary Cells

It All Starts with the Right Cells

As researchers continue to strive toward the development of personalized medicines, using ethically sourced human biological material is becoming increasingly important for conducting specialized cell-based assays. To ensure drug discovery and development stages are substantially validated, it is paramount to use cells of the highest quality. Thus, a key factor for efficient, high-quality, cell-based research is working with a reliable supplier who not only values sample integrity, security, and compliance, but who can also support your specific requirements.

STEMCELL Technologies accommodates your unique needs with personalized service and customizable products, including products that meet specific isolation and anticoagulant requirements, custom cell isolation kits, cell culture media, and more. Additionally, with the option to reserve multiple lots to prescreen cells for your applications, we help you get the cells you need.

Why Use Human Primary Cells from STEMCELL Technologies?

  • Choose cells that are more physiologically representative of cells in vivo.
  • Access donor samples collected using regulatory authority-approved consent forms and protocols.
  • Request custom products for non-standard cell types or collections with specific requirements.
  • Reserve large numbers of cryopreserved cells and start experiments on your schedule with cells you've already tested.
  • Reduce time spent collecting and culturing cancer-sourced primary cells.

Custom Primary Cell Products*

In addition to the hundreds of ready-made, "off-the-shelf" primary cell products from peripheral blood, cord blood, and bone marrow that we provide, STEMCELL can also support your complex research projects with products customized to your specific requirements. Examples include:

  • Rare or difficult-to-isolate hematopoietic cell types (normal and diseased, including cells from patients with autoimmune diseases, diabetes, asthma, cancer, etc.)
  • Cells that meet specific donor recruitment criteria
  • Collections obtained using alternative anticoagulants
  • Products in alternative size formats, e.g. bags, vial sizes, requested cell counts, etc.
  • Donor-matched collections for fresh and/or cryopreserved cells, e.g. whole blood, leukopaks, isolated cells, plasma, serum, etc. from the same donor

Cell Characterization Services

Save time by letting STEMCELL characterize your cells. Reserve multiple lots before selecting your lot of interest based on the test results. Characterization services include:

  • Viral screening: e.g. lymphocytic choriomeningitis virus (LCMV) status, cytomegalovirus (CMV) status, Epstein-Barr virus (EBV) status, and others
  • High-resolution human leukocyte antigen (HLA) typing: Class I and II
  • Blood type: ABO/Rh factor
  • Genotyping: CD16, CD32, and Killer Ig-Like Receptors (KIR)
  • Phenotyping
  • FACS analysis

Donor Specifications

Leverage our robust donor pool for your specific donor specifications, including:

  • Donor demographics: age, sex, weight, height, and ethnicity
  • Donor attributes: BMI, smoking status, and vaccination status
  • Donor request: recall, repeat, and diseased patient donors

Donors are screened for HIV-1, HIV-2, hepatitis B, and hepatitis C. The donor demographics and testing information for a specific product can be found on the Product Information Sheet (PIS) and the Certificate of Analysis (CoA), respectively. Additional viral screening, including LCMV status, CMV status, EBV status, human T cell lymphotropic virus (HTLV) status, syphilis status, West Nile virus status, COVID-19 history and vaccination status, and others, may be requested. Learn more about our Donor Viral Screening Policy.

If donors with specific characteristics are unavailable, we are able to request donors of choice. Please note that there may be an additional fee and lead time associated with the request.
