IMMUNOLOGY RESEARCH PRODUCTS Primary Cells It All Starts with the Right Cells Sourcing Isolation Activation, Expansion, & Differentiation Analysis Starting with the right primary cells as the foundation for your experiments is the first step towards success in your research. Choose from a wide range of fresh or cryopreserved human primary cells isolated from peripheral blood, cord blood, bone marrow, and mobilized peripheral blood. 1,2 Cryopreserved immune and progenitor cells are isolated from full-size Leuko Paks (leukapheresis preparations) or entire umbilical cords and are ready to use upon receipt. For users requiring fresh unprocessed tissue samples, whole peripheral blood, whole bone marrow, and Leuko Paks are also available. Cells are shipped with a Certificate of Analysis indicating guaranteed Quality Control testing results including cell count, viability, and purity. All human primary cell products are ethically sourced using informed consent forms (ICFs) and protocols approved by either the Food and Drug Administration (FDA) or an Institutional Review Board (IRB), ensuring the protection of personal information and donor anonymity. 3 Why Use STEMCELL's Primary Cells? PHYSIOLOGICAL RELEVANCE. Choose cells that are physiologically representative of cells in vivo. ACCESS. Obtain large lots of cryopreserved cells, including cells that are rare or difficult to isolate, reducing inter-assay variability. CONVENIENCE. Start your experiments according to your schedule, without being restricted by the availability of tissue samples. FLEXIBLE HOLD POLICIES. Reserve large numbers of cryopreserved cells while you test in your specific applications. See pages 16 and 17 for a complete listing of mononuclear cells, isolated subsets, plasma, and unprocessed tissues from normal and diseased donors, or visit www.stemcell.com/primarycells. Figure 1.

Fresh products currently available in the United States and Canada (excluding Quebec). Please contact Product and Scientific Support (techsupport@stemcell.com) for further information. 3. Leuko Pak,, and Bone Marrow (LP, WB, and BM) Donor Screening: Donors are screened for HIV (1 & 2), Hepatitis B, and Hepatitis C. Cryopreserved LP, WB, and BM: Products are shipped with negative test results from donor screening that is done within 9 days of collection. Fresh LP, WB, and BM: If the donor has been screened within 9 days of donation the product will be shipped with negative test results from donor screening. If the donor has not been screened within 9 days of collection, a test sample will be taken at the time of donation and the product will be shipped before the screening results are available. In the unlikely event that a test result is positive, the customer will be contacted as soon as possible (usually within 2-4 business days from the time of shipment). Cord Blood (CB) Donor Screening: Testing for HIV-1 and 2, Hepatitis B, and Hepatitis C is performed on a maternal blood sample and/or on a sample of the donated cord blood. Cryopreserved CB: Products are shipped with negative test results from donor screening. 4 STEMCELL Technologies Inc.

IMMUNOLOGY RESEARCH PRODUCTS EasySep TM Fast and Easy Immunomagnetic Cell Isolation EasySep is a powerful immunomagnetic cell isolation platform that combines the specificity of monoclonal antibodies with the simplicity of a column-free magnetic system for fast and easy isolation of highly purified cell populations that are immediately ready for downstream applications. Cells are targeted for either depletion (negative selection) or selection (positive selection) using antibody complexes directed to specific cell surface antigens. The antibody complexes link targeted cells to magnetic particles. Labeled cells are pulled to the sides of the tube when the sample is placed in an EasySep magnet. Magnetically labeled cells will remain in the tube while the untouched cells can be simply poured or pipetted off into a new tube. Why Use EasySep? FAST AND EASY. Isolate cells from virtually any sample source in as little as 8 minutes without columns or washes. GENTLE. Obtain viable and functional cells that are immediately ready for downstream applications.

4 5 IMMUNOLOGY RESEARCH PRODUCTS SepMate TM Hassle-Free Isolation SepMate is a specialized tube for fast and easy isolation in just 15 minutes. The SepMate tube contains a unique insert that prevents the density gradient medium 1 (e.g., Ficoll-Paque or Lymphoprep ) and blood sample from mixing. The density gradient medium is pipetted through a central hole in the insert, and the sample is poured or rapidly pipetted on top of the insert. This eliminates the need to carefully layer the sample directly onto the density gradient medium, an otherwise time-consuming and highly laborious step. Only 1 minutes of centrifugation are required, and this step can be carried out with the brake on, further reducing the total time necessary for separation. After centrifugation, plasma and s are simply poured into a new tube. SepMate is registered as an In Vitro Diagnostic (IVD) device in select regions. 1,2 Why Use SepMate? EASY. Avoid the need for slow and laborious sample layering over the density gradient medium. FAST. Isolate s directly from whole blood in just 15 minutes. CONSISTENT. Eliminate errors and minimize variability between separations. VERSATILE. Combine with RosetteSep to isolate purified cell subsets from whole blood in 25 minutes. 3 REGISTERED.

Select RosetteSep products carry the CE mark and are suitable for IVD applications in countries where the CE marking is recognized. Did You Know? Lymphoprep has the same density as Ficoll-Paque, is more cost-effective, and can be substituted for Ficoll-Paque without any need to change your existing protocols. 12 STEMCELL Technologies Inc.

RosetteSep TM Unique Immunodensity Cell Isolation RosetteSep is a fast and easy immunodensity procedure for the isolation of untouched cells directly from whole blood. By crosslinking unwanted cells to red blood cells (RBCs) present in the sample, RosetteSep eliminates the need for a separate magnetic separation step because cells are purified during standard density gradient centrifugation. This approach significantly reduces sample handling time and maximizes convenience. Typical RosetteSep Protocol 1 2 3 4 Add RosetteSep Enrichment Cocktail. Layer over density gradient medium.
