Interested in obtaining products for research? We offer a variety of products and services that can assist you and your company with research activities. Services we offer include:

  • Blood products for in-vitro use
  • Blood products for in-vivo use (clinical trials)
  • Clinical laboratory testing services
  • Research donor selection and recruitment

Products for In-Vitro Use:

The Stanford Blood Center provides blood products for in-vitro investigational use. Tubes or whole units of blood may be collected from individuals selected by the researcher or recruited by the Blood Center. Products collected for in-vitro investigational use are not routinely tested for infectious disease markers, although donor pre-screening can be arranged. Because products for in-vitro use do not meet the same safety criteria as blood products for transfusion, these components must not be used for infusion or for manufacturing into infusible products. Please contact our Customer Relations Department at 650-724-2997 for more information.

Products for In-Vivo Use (Clinical Trials):

The Stanford Medical School Blood Center collects blood products for investigational in-vivo use. Products may be collected from patients for re-infusion into the same patient (autologous donors), from relatives of patients (directed donors) or from normal healthy donors (allogeneic donors). IRB approval is required for all trials involving investigational in-vivo use of blood products. For information about our clinical trials program, please contact Customer Relations at 650-724-2997.

Tubes

Red top (clot), 6mL

There is no additive or anticoagulant added to this tube.

Used for specific procedures requiring serum.

Purple (lavender) top (K2 EDTA, spray-coated plastic), 6 mL

Contains 0.07 mL of 15% buffered solution or the calculated equivalent of 10.5 mg EDTA (K 3). EDTA or ethylenediamineteteracetic acid chelates calcium to prevent clotting.

Used primarily for hematology and specific chemistry procedures requiring plasma or whole blood. EDTA whole blood samples are superior for flow cytometry studies because the formation of artifacts is prevented, even after prolonged standing.

Purple (lavender) top (K2 EDTA, spray-coated plastic), 4 mL

Contains 0.050 mL of 15% buffered solution or the calculated equivalent of 7.5 mg EDTA (K 3). EDTA or ethylenediamineteteracetic acid chelates calcium to prevent clotting.

Used primarily for hematology and specific chemistry procedures requiring plasma or whole blood. EDTA whole blood samples are superior for flow cytometry studies because the formation of artifacts is prevented, even after prolonged standing.

Yellow top (ACDA-liquid), 8.5 mL

Contains 1.50 mL of anticoagulant Acid Citrate Dextrose Solution (A). ACD-A contains nutrients to help maintain the whole blood for several weeks.

Used primarily for specific immunohematology and histocompatibility procedures requiring preservation of whole blood.

Green top (Heparin), 10 mL

Contains 143 USP Units of Sodium Heparin. Heparin inhibits thrombin to prevent clotting.

Used for chemistry and selective hematology determinations. This anticoagulant is best for prevention of hemolysis and for osmotic fragility tests.
