The EasySep™ Human IgG+ Memory B Cell Isolation Kit isolates IgG+CD27+ B cells from fresh or previously frozen peripheral blood mononuclear cells (PBMCs) or leukapheresis samples. First, CD27+ cells are isolated by column-free immunomagnetic positive selection using EasySep™ Releasable RapidSpheres™. Then, bound magnetic particles are removed from the EasySep™-isolated CD27+ cells, and unwanted non-B cells, as well as IgM+, IgD+ and IgA+ cells are depleted using EasySep™ Dextran RapidSpheres™. The final isolated fraction contains IgG+CD27+ memory B cells, which readily secrete IgG in culture supernatants in the presence of appropriate stimuli.
