The EasySep™ Release Human CD19 Positive Selection Kit is designed to isolate CD19+ cells from fresh or previously frozen peripheral blood mononuclear cells or washed leukapheresis samples by immunomagnetic positive selection.Desired cells are labeled with antibodies and magnetic particles, and separated without columns using an EasySep™ magnet. Unwanted cells are simply poured off, while desired cells remain in the tube. Then, bound magnetic particles are removed from the EasySep™-isolated CD19+ cells, which are immediately available for downstream applications. Following cell isolation with this EasySep™ Release kit, antibody complexes remain bound to the cell surface and may interact with Brilliant Violet™ antibody conjugates, polyethylene glycol-modified proteins or other chemically related ligands. Products are for Research Use Only, Not for Diagnostic or Therapeutic use, and are not to be administered to humans.
