LDS-751 is a nucleic acid stain. In Vitro: The LDS-751 permits the discrimination of intact cells from residual erythrocyte ghosts, platelets and damaged nucleated cells. The forward and orthogonal fight scattering signals of the intact cells, identified by LDS-751 staining allow a clear separation between the major leukocyte populations since the damaged nucleated cells, erythrocytes, erythrocyte cell ghosts and platelets are removed from the display^[1].
