The RosetteSep™ HLA Myeloid Cell Enrichment Cocktail is designed to enrich myeloid (CD33+) cells from whole blood by negative selection for lineage-specific chimerism analysis. Unwanted cells are targeted for removal with Tetrameric Antibody Complexes recognizing CD3, CD8, CD19, CD56 and glycophorin A on red blood cells (RBCs). When centrifuged over a buoyant density medium such as RosetteSep™ DM-M (Catalog #15725), the unwanted cells pellet along with the RBCs. The purified myeloid cells are present as a highly enriched population at the interface between the plasma and the buoyant density medium. The desired cells are immediately ready for chimerism analysis. This kit carries the CE mark and is available as a Class I in vitro diagnostic device in the European Union and Australia.
