The EasySep™ Direct Human NK Cell Isolation Kit is designed to isolate NK cells from human whole blood by immunomagnetic negative selection. The EasySep™ Direct procedure involves labeling RBCs, platelets and unwanted cells present in human whole blood with antibody complexes and magnetic particles. The magnetically labeled RBCs, platelets and cells are separated from the untouched desired cells by using an EasySep™ magnet and simply pouring or pipetting the desired cells into a new tube.
