Density gradient media separate cells by density during centrifugation, most often to isolate mononuclear cells (PBMC) from peripheral blood or bone marrow. They are used in research and to prepare starting material for cell therapy. Buyers compare research against clinical or GMP grade, the density that suits the target cell, and the chemistry: Ficoll-type polysucrose, Percoll-type colloidal silica, or iodixanol, plus dual-density media for granulocytes.
