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. The CD19 antigen is expressed on mature B cells and B cell progenitors but is lost upon maturation to plasma cells. It is also expressed on follicular dendritic cells.

Data and Publications
Starting with a single-cell suspension of human PBMCs, the CD19+ cell content of the isolated fraction is typically 97.7 ± 2.3% (mean ± SD using the purple EasySep™ Magnet). In the above example, the purities of the start and final isolated fractions are 6.2% and 98.0%, respectively.
