This product is designed to enrich group 1, 2 and 3 innate lymphoid cells (ILC1, ILC2 and ILC3s) from single-cell suspensions of mouse tissues by negative selection. Unwanted cells are targeted for removal with biotinylated antibodies directed against non-ILCs and streptavidin-coated magnetic particles (RapidSpheres™). Labeled cells are separated using an EasySep™ magnet without the use of columns. Unwanted cells remain in the tube as desired cells are simply poured off into a new tube. Isolated cells are immediately available for downstream applications such as flow cytometry and cell sorting.
