The EasySep™ Dead Cell Removal (Annexin V) kit is designed to deplete apoptotic (Annexin V+) cells from cell culture or tissue preparations by immunomagnetic negative selection. Unwanted cells are labeled with Annexin V, antibodies and magnetic particles, and separated without columns using an EasySep™ magnet. Labeled cells are separated using an EasySep™ magnet without the use of columns. Desired cells are simply poured off into a new tube. Annexin V binds phosphatidylserine on the outer leaflet of the cell membrane during apoptosis.
