Lymphosep - Lymphocyte Separation Medium is a sterile, iso-osmotic, low viscosity solution for density centrifugation yielding a clear separation of lymphocytes from heparinized or defibrinated human blood. Lymphocytes are isolated by layering diluted, heparinized blood over a solution of sodium diatrizoate that contains a polysaccharide. This polysaccharide aggregates the erythrocytes so that they can be sedimented by low centrifugation. The less dense lymphocytes remain as a clearly defined band at the plasma Lymphosep interface.
