CD14+ monocytes are responsible for phagocytosis of foreign substances in the body and are capable of killing infected host cells via antibody-mediated cellular cytotoxicity. Under the right culture conditions, monocytes can differentiate into dendritic cells, Langerhans cells, or macrophages.
CD14+ monocytes are isolated from mononuclear cells by positive selection using immunomagnetic cell separation procedures. Negative selection is also available at your request.
Use fresh CD14+ monocytes immediately upon receipt. Be sure to remove HypoThermosol® prior to use. If not used immediately, temporarily store cells at 0-4°C or freeze for long-term storage.
For cryopreserved CD14+ monocytes, either prepare cells for long-term storage in Liquid Nitrogen vapor phase or thaw for use. Storage in liquid phase nitrogen is NOT recommended. Short-term storage of cells (less than 2 weeks) at -80°C is acceptable but should be minimized to ensure maximum stability. Once thawed, samples must be used immediately.
Testing: Donors are tested for HBV, HCV, HIV, HTLV, WNV, Trypanasoma cruzi, and Syphilis.
