Product Description

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 peripheral blood CD56+ natural killer cells are enriched by means of negative selection. Isolated cells are characterized by flow cytometry to ensure a highly pure and viable cell population.

*Our CD56+ natural killer cells are isolated by means of negative selection. However, we do offer the isolation of CD56+ natural killer cells by positive selection as a custom order. Please inquire to obtain pricing for the positive selection of CD56+ natural killer cells.

Cells were obtained using Institutional Review Board (IRB) approved consent forms and protocols.
