Clinical Grade Non-Transfusable Mobilized Peripheral Blood CD56+ Natural Killer Cells, G-CSF, Frozen
Natural killer (NK) cells play a key role in the innate immune system. These lymphocytes react to certain infections and malignancies by direct cytolysis of infected or transformed cells and by secretion of potent immune mediators. NK cells have the ability to recognize foreign or stressed cells that lack antibodies and major histocompatibility complex (MHC) class I proteins on the surface, which would normally go undetected by other immune cells. However, NK cells express an array of inhibitory receptors that recognize self-molecules. If not restrained by inhibitory receptors recognizing MHC class I proteins on the surface of self-cells, NK cells are able to kill normal, healthy cells.
Human mobilized peripheral blood CD56+ NK cells are enriched from the total cell population using direct immunomagnetic anti-CD56 beads. All cell isolation components, including reagents, tubing sets, instruments, and buffers, are manufactured and controlled under an ISO 13485 certified quality system under FDA oversight. Cell culture procedures, including open manipulation of vials, final filling, and closure of finished products, are performed inside ISO 5 air quality processing chambers located within an FDA-registered cell manufacturing facility. Isolated primary cells are characterized by flow cytometry to ensure a highly pure and viable cell population.
Cells were obtained using Institutional Review Board (IRB) approved consent forms and protocols. All reagents and devices used to collect and separate the cells are certified clinical grade. This item is for research use only.
