purified mouse B cells from single-cell suspensions of splenocytes or other tissue samples by immunomagnetic negative selection, with the EasySep™ Mouse B 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™ negative selection procedure, unwanted cells are labeled with antibody complexes and magnetic particles. The following unwanted cells are targeted for removal: CD11b, CD4, CD8a, Ly6G/C, Ter119, CD43, CD49b, and CD90.2. The magnetically labeled cells are then separated from the untouched desired B cells by using an EasySep™ magnet and simply pouring or pipetting the desired cells into a new tube. Following magnetic cell isolation in as little as 15 minutes, the desired B cells are ready for downstream applications such as flow cytometry, culture, and cell-based experiments. For isolation of B cells expressing CD11b or CD43, we recommend using the EasySep™ Mouse Pan-B Cell Isolation kit (Catalog #19844).
