Natural Killer NK Cells

NK (Natural Killer) Cells

Natural killer (NK) cells are cytotoxic effectors of the innate immune system with a primary role in immunosurveillance. They are capable of mounting rapid immune responses against foreign pathogens and tumor cells. Primary CD56+ NK cells can be isolated from leukapheresis material (Leukopaks) via positive or negative immunomagnetic separation.

Scientists are working on autologous and allogeneic NK cell-based cancer immunotherapies (i.e., CAR-NK cells) to treat a variety of blood and solid tumor cancers like lymphoma, leukemia, melanoma, and breast cancer.

Isolated Cell

NK cells isolated from Leukopaks are available through positive or negative immunomagnetic bead separation. Positive immunomagnetic bead separation - beads bind to the target cell population from the heterogenous mixture; labeled target cells remain while the non-target cells are removed. Negative immunomagnetic bead separation - beads bind to the non-target cell population to deplete them from the mixture leaving behind the unlabeled cells of interest.
