Summary
LDS-751 is a nucleic acid stain principally detecting DNA. LDS-751 has high affinity for DNA and undergoes fluorescence enhancement upon binding, but with maximal emission at 670 nm. LDS-751 and Thiazole orange are used to differentiate erythrocytes, platelets, reticulocytes, and nucleated cells, and both can be excited at 488 nm [1] [2] [3] .
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] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
