Bone marrow CD34+ cells contain hematopoietic stem and progenitor cells and are known to differentiate into all the various blood cell types.

• Ready to use
• High purity with >90% CD34+ cells
• Wide donor variety
• Large lot sizes (if large lot sizes are not required and more naive HSCs are desirable you may be interested in cord blood derived CD34 ± cells)

Lonza bone marrow CD34+ cells are isolated from bone marrow mononuclear cells (MNC) by positive immunomagnetic separation and are guaranteed to have a purity of ≥90%. HIV-1, hepatitis C, and hepatitis B are not detected for all donors and/or cell lots. Fresh bone marrow CD34+ cells are offered in various sizes and require a minimum order quantity of two vials per donor.

HPGM® Hematopoietic Growth Medium is recommended for optimal performance in serum-free culturing (additional cytokines may be necessary depending on application) Alternative media containing serum may also be acceptable.

Lonza guarantees the performance of Clonetics®/Poietics® cells only if appropriate Clonetics®/Poietics® media and reagents are used exclusively and the recommended storage and use protocols are followed.

Complex research often calls for flexibility. That's why we offer isolated and purified bone marrow CD34+ cells as well as unprocessed bone marrow in case you need to isolate your own cells. Bone marrow CD34+ cells are ideal for studies requiring a large number of cells from a single donor or studies investigating differences in cells of donors of various ages, genders, or ethnicities. If however, your studies demand more naïve cells, cord blood CD34+ cells may be the better choice.
