BeaverBeads™ Human Neutrophil Isolation Kit is designed for the isolation of neutrophils from fresh human peripheral blood using a negative selection strategy. The principle of this kit is based on labeling non-target cells with biotin-conjugated monoclonal antibodies, followed by the removal of these labeled cells using streptavidin-coated magnetic beads. During magnetic separation, the magnetically labeled non-target cells are retained by a magnetic separator, allowing untouched, bead-and antibody-free human neutrophils to be efficiently collected from the supernatant. The separation procedure requires the use of a magnetic separator.
