Easily isolate highly purified and magnetic particle-free human central (CD3+CD8+CD45RO+CD62L+) and effector (CD3+CD8+CD45RO+CD62L-) memory CD8+ T cells from fresh peripheral blood mononuclear cells (PBMCs) or washed leukapheresis samples, using immunomagnetic positive selection, with the EasySep™ Human Central and Effector Memory CD8+ T Cell Isolation Kit. Widely used in published research for more than 20 years, EasySep™ combines the specificity of monoclonal antibodies with the simplicity of a column-free magnetic system.

In this EasySep™ positive selection procedure, desired cells are first labeled with antibody complexes recognizing CD62L and magnetic particles called EasySep™ Releasable RapidSpheres™. Unlike traditional magnetic particles, which stay bound to the target cells, these RapidSpheres™ have a releasable feature. After separation using an EasySep™ magnet, bound magnetic particles are removed from the EasySep™-isolated CD62L+ cells using a release agent, and unwanted CD45RA+ and non-CD8+ T cells are targeted for depletion using antibody complexes and EasySep™ Dextran RapidSpheres™. The effector memory CD8+ T cells are isolated from the CD62L- fraction using antibody complexes and EasySep™ Dextran RapidSpheres™. 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.
