The EasySep Non-Human Primate B Cell Isolation Kit is designed to isolate untouched and highly purified B cells from fresh or previously frozen non-human primate peripheral blood mononuclear cells (PBMCs) in as little as 20 minutes by immunomagnetic negative selection. The EasySep procedure involves labeling unwanted cells with antibody complexes and magnetic particles. The magnetically labeled cells are separated from the untouched desired cells by using an EasySep magnet and simply pouring or pipetting the desired cells into a new tube. Isolated cells are immediately available for downstream applications such as flow cytometry culture or DNA/RNA extraction.
