Whole Blood Products and Donor Program

Biological Products has an independent donor pool of healthy, reliable blood donors, managed by an IRB approved protocol and consent process.

We have capabilities to customize our whole blood draws to use lot or catalog number-specific anticoagulant, tubes, syringes, or any other products required, and we specialize in customizing normal controls draws to mimic clinical studies. Please contact us for more information regarding special draw requirements.

Healthy donors can be selected to fit certain criteria, and recalled for longitudinal studies. Biological Products has a database of donor demographic data, including information such as high resolution HLA typing, CMV status and other donor selection criteria.

Isolated Cell Types

Biological Products has capabilities to isolate any cell type(s) from whole blood up to 500mL, cord blood units, or 1/4 to a full leuko pack, using positive or negative isolation techniques with a magnetic bead system. Cells are drawn, processed, and delivered to the Seattle area in the same day, or shipped fresh or frozen overnight.

Customized selection protocols and strategies can be established to fit project needs. Years of experience allow Biological Products to consult to maximize efficiency and cost effectiveness. QC is performed for all processed cells to guarantee sterility, viability, and purity, providing detailed report following the cell delivery.

For pre-clinical assays, Biological Products has machines and reagents that are FDA approved as IDE and IND.

Frozen Cell Bank

Biological Products maintains a frozen cell bank of PBMCs and Isolated cell types.
We have high resolution HLA and purity data for all frozen cells.

Biological Products maintains a donor pool, so most frozen cells can be used to screen donors, who can be recalled for special projects.

In addition to the frozen cell bank, customized freezing services can be applied to large or small cell orders and can be performed according needs of the researcher.

Become a Donor: Volunteers Needed for Research Studies

Biological Products provides samples of blood and other body tissues to researchers working to learn how cells, genes, the body’s chemistry and systems change in health and disease.

We are actively seeking out willing and healthy volunteers to provide blood samples for research projects at various research institutions. Volunteers will be screened and entered into a pool to be called on as needs arise. Volunteers may be asked to donate samples many times, depending on research needs.

Volunteers are paid for their time and availability.

Samples are collected at: 921 Terry Ave, Seattle, WA 98104 and/or 1551 Eastlake Ave E, Seattle, WA 98102
